If my psu is pushing air out of the case and all we're supposed to need is one push and one pull, would I be fine with just one case fan pushing air into the case? Since the psu will be pulling it out...
What's a good shutoff temp for case fans?
>>55614842
If you can control the rpm, why not just have them ramp up when the temperature goes up? Silence is good, but even the littlest airflow makes temps drop quite nicely
>>55614842
I agree with that other anon, keep it running.
You should not hear a fan under 500rpm anyway, unless you put your ear next to it.
Keep in mind some fans just don't work at low rpm. Avoid them.

Can I put a psu that was made for cases with top psu on a bottom psu case?
I want to fit 2 80mm fans at the back of the case to push air out, but i only have one non cpu fan header, which is currently powering a 200 mm fan at the front of the case. If i use a splitter to power 3 fans from the case fan header, will i lose any power? Also i have an after market heatsink on the cou, should i have the fan pushing air through it from the front, or pulling from the back?
I'm looking for info regarding the noctua NF P12
I own a few, but the wires are cut, and I know they are supposed to come with different wires depending on the speed you want
How should I wire these fans (on a molex for example) to get the fans to work ? I'm afraid to burn then with improper wiring
>>55615221
Yes
Fuck sake why are all good radiator fans 4pin? Due to reasons I need some 3 pin fans to replace my barely satisfactory SP120's for some extreme air cooling and its a fucker to find 3 pin alternatives with better performance.
>>55615328
The screws won't work with the case if I flip it with the fan down, I'm really afraid that the psu will blow itself because it wasn't made for bottom cases.
What's the best pwm signal generator + power supply for some loud as fuck 4 pin server fans?
There are a few chink shit options on ebay that i'd like to avoid
>inb4 oscilloscope
>>55615290
It depends how much current the fans are pulling. Can you not use molex?
>>55615344
If you flip the psu down it'll still work fine. No such thing as a top or bottom designed psu last time I checked.
>>55615341
Isn't the 4th pin just for extra shit like speed control? 4 pin should still fit onto 3 pins, Plus usually radiator fans will want to adjust rpm based on cpu temps...
>>55614604
Which one's better?
>Kraken X61
>Corsair h110i
The corsair looks better built, but I'm reading that the Kraken is supposedly better
>>55615365
Isn't the 4th pin just for extra shit like speed control? 4 pin should still fit onto 3 pins,
It won't because most 3 pin female connections are exactly 3 pins wide and I don't want to cut the connector to make 4 pin fit as its part of a fan controller.
>Plus usually radiator fans will want to adjust rpm based on cpu temps...
It isn't for cooling a cpu.
>>55615365
Would molex make the fans run at a constant speed? I liked the idea of the pull and push fans running off the same pins, because they would run at the same speed right, or at least they would change speed depending on the temp inside?
>>55615404
Correct me if I'm wrong but we're talking about connecting these to a motherboard fan header? 4 pin should still fit onto a 3 pin header.
And if you meant something else, I apologize.
Also, aren't radiator fans just mostly standard 12 or 14cm case fans?
>>55615414
Yep, no speed control without an external controller with molex
>>55615462
Do i still get speed control with only three pins? Also thanks for all your help :)
>>55615462
>Correct me if I'm wrong but we're talking about connecting these to a motherboard fan header?
We are not. My case has a voltage controleld fan controller and it is exactly 3 pins wide with the housing (i.e its not open like motherboardh eaders are).
However you have prompted me to do some research and it appears I can get a different cable (primarily 3 pin to mini 3 pin) which is exactly what I need. You see i'm cooling my gpu with an aftermarket heatsink and naturally normal fans won't fit onto the board's fan header. Given 4/3pin to mini 4/3 pin adapters are a thing I can use a Y splitter for the two fans and connect them directly to the gpu itself.
The next question is do I want to replace the SP120's themselves? Hmmm....
>>55614722
If psu the only pulling the hot air out, its going to die right after warranty periods.
If you dont plan to use the setup for more than two years, go ahead.
Even a shitty oem will include an 80mm fan at the rear for a reason.
New sg13 owner here
My idle temps are 45°... And playing csgo it goes up to 70°.
And, the IO shield gets VERY hot.
However, making the fans spin faster or slower does NOTHING to the temps. Should I be worried? I'm using a AR06 to cool the cpu. Just that the PSU is rated to 40°, and it gets to 42°...
you guys would be jealous of my open air core x9 with fans ziptied everywhere. too bad im not gonna turn my phone on and take pics.
>>55614604
Well when I upgraded to a dual CPU xeon I found that shoving a big arse fan in the CD bit worked a charm!
I'm gonna ask again in this thread. My old Fander CPU fan is dying (RIP in pierogi). Which of these 2 should I choose to replace it: Arctic Cooling F9 or DeepCool UF92?
Where on earth do you buy Reeven Euros fans? Some of them have some mighty impressive specs but sourcing seems to basically be impossible for the common pleb.
>>55615666
Oh dear! I don't like the looks of them trips!
>>55615700
Dubs!
>>55615549
in theory, yes. not pwm, of course.
in practice, it depends on the mobo.
>>55615835
>>55615549
I use something similar to this for speed control, came with my cpu cooler.

>>55615666
That's actually a pretty awesome idea I never thought of!
Didn't some older computers have something you put in place of the disk drive with 2 small fans in it?
Seriously Nvidia?
Aluminum heatsink?
Nvidia needs a new lease on life.
which 80mm x 25 mm fans have the most cfm? noise is not an issue
I need intake fans which make some light since my pc's inside is quite dark. Any suggestions?

What's the best top blow cooler to cool down the VRM and the north bridge?
So /pcg/
I'm building my first PC on Wednesday and I am concerned about the cooling.
I have the stock case fan coming in with my case and another case fan bought seperatly.
If this is my build, will only 2 case fans suffice?
http://pcpartpicker.com/list/gyJmqk
>>55616376
Most likely - none of the parts you have there are known for their high heat output so as long as you keep airflow unobstructed I doubt anything will reach critical temps.
>>55616250
>Liquid cooling is just a meme, right?
It costs shittons for very little gain in performance, but it's the only way to keep a 250W GPU actually quiet as in "is my PC even on?".
I got an idea for an awesome case mod I'd like to build but I need to find fans that have aspect ratio close to 4:3, preferably 120x92mm, but I'm quite new to building PCs and don't seem to find any fan manufacturer who has them. Pic for reference of what I'm looking for

Guys does watercooling even worth it ? I have 212x and it does the job just right with my 4690k
>>55616250
>>55616571
Watercooling - as in custom loop - is only really viable if you meet most of the following criteria:
1) Are a balls-to-the-wall overclocker.
2) Have high end parts at time of purchase
3) Desire extreme silence on said hig hend parts
4) Use small form factors (as naturally fuckoff huge heatsinks won't fit)
5) Have loads of dosh
If the majority of those points don't apply to you then watercoolnig is not for you.
How good are fractal design silent series r3 fans? I have three of them at the moment, 2x120mm and 1x140mm, but are thinking of buying some new ones.
Are there any at rougly the same price that are better, and with the same sound level as them?
>>55616268
About to build my first pc and my setup will look very similar. Any reason as to why you're not using the Fractal Design fans that comes with the case on top and bottom? Are the cables from the psu preventing you from doing that?
>>55616640
none of them applies to me.
>>55616250
Just get Hyper 212x or 212 Evo, you'll be fine.
>>55616427
Bait
>>55615549
Get fans that can share PWM signal like Arctic Cooling.
You can than hook all CPU+case fans to single header if you want and still have fans speed controllable in software (BIOS/speedfan whatever you want).
This is the only proper way to do PC cooling.
>>55616401

if you guys have a mount for a side panel fan you really should use it. put an exhaust fan on there and my gpu temps under load went from 83 to 72c, allowing me a lot more thermal headroom to get a good overclock
>>55617210
Using the side panel mount makes my Define R4 a lot more noisy. I prefer the silence.
>>55615666
i did this exact same thing when i built a pc in an emachines case
>>55617227
I have an r5, there's lots of things I've done to it to make it less silent (mostly the watercooler I installed makes a fuckton of noise) but the side panel fan is near silent. Maybe it's a bad fan?
Why don't people use the Be Quiet! Slient Wings 2? Its a hybrid between static pressure and high air flow, has the best noise/performance ratio at its max speed and looks nice
>>55616679
They Fractal fans while decent, are way louder than the Noctua fans. My build is actually quieter now with 2 extra fans, than it was last month when I was only using the 2 fans that came with the case.
As for the bottom fan, yeah the PSU cables are in the way. Also, there's no dust cover for the top of the case, so I didn't really want to open up the vents.
>>55617325
Silent Wings are so expensive though... What's wrong with Pure Wings 2?
Do I even need anything better than stock cooling, if I dont intend to overclock?
I mean, every time I ask outside /g/, people tell me to get some monster coolers for huge price. If my CPU came with stock cooler, why replacing it?
I know that some CPUs like (in)famous i7-6700K comes without stock one, but does it realyl need anything better than, say, 212 Evo?
>>55617435
pure wings are slightly louder, why do people opt for noctua fans and not slient wings 2? If you look at some performance and noise graphs of the fans, you will see that slient wings 2 has a better noise/performance, and I still don't get why people go with the noctuas
>>55617451
If you get a dual tower cooler this will mean that your fans will need to do less cooling thus lower rpm, as a result lower noise.
>>55617451
i5 6700k is infamous? what the fuck
it's pretty much the strongest desktop processor in terms of gaming out there right now...
>>55617475
140mm silent wings 2 are 25 €
140mm noctua redux are 16 €
no fan should cost more than 20 €
>>55617237
Nah, I have some Noctua NF-A14s that all work fine. There's just a perceptible additional bit of airflow noise at idle that gets on my nerves with the soundproofed cover removed. My temps are good anyway with two front intakes and one rear exhaust.
>>55617550
Is that the only reason? Also since prices are different in other locations that not a really valid reason
The best static pressure fans are the gentle typoons in terms of noise/performance, why don't people get them instead of the noctuas?
>>55617599
For ages they were borderline impossible to buy.
>>55617599
To add onto this I feel like people just fall for marketing and don't look into other fans like Gentle Typoons, Noiseblocker NB eLoop, Slient Wings 2 and Vadar. If you want the best of the best you get the Gentle Typoons for your radiator or cpu cooler, and the Slient Wings 2 for your places where there is not much obstruction like in front of the hard drive bays.
>>55617642
I can get them right not for £20 and theres tons in stock in the UK where I am, not sure about other areas
>>55617550
be quiet fans are garbage. My silent base 800 case came with 3 of those and within 6 months they were all whining and buzzing. My 6 year old noctua fan sitting on my heatsink is still spinning quietly. Every single fan i've ever owned that wasn't noctua have broken down within a few years. You get what you pay for when buying noctua.
>>55617672
maybe you're just unlucky, I don't see people complaining about the be quiet fans but you, just because it happened to you doesn't mean they're garbage
>>55617528
I said "infamous" simply because when I say that I wanted to get that model, everyone, even guy at shop I asked, says "why you need i7, when you can get i5" and "oh another poor faggot that felt for 'I need i7' meme". That guy at shop at least agreed, when I said how I bought i5-750 6 years ago and it serve me since then and that I want next cpu to last at least 3-4 years too.
"Wanted" because I had to kill my inside hype for upgrade, when I realized how much they cost. And I have no idea if said price will drop any time soon.
>>55617500
What if Im okay with some noise?
All I want to know if I really need something better than 212 Evo, if I would have case with proper airflow. Like if it wont get overheat.
>>55617856
if you're ok with noise then evo is good
>>55617856
I switched from a hyper 212 evo to a kraken x61
the thermal headroom I got let me go from 4.3 ghz to 4.6. If I wanted I could probably take it to 4.7 That's the difference. You have to decide if that performance boost is worth the ~70 ish dollars you have to pay more for the kraken...
>>55617666
>I can get them right not for £20 and theres tons in stock in the UK where I am, not sure about other areas
Thats because nidec have started selling them to plebs. After scythe lost the license gentle typhoons basically fell off the face of the earth for regular consumers as nidec was only interested in OEM deals.
>>55617984
Im living in Poland, so every price increase in USD for you must be multiplied by 4,9 (4 + 23% VAT) or 4,5 if we just translate price in EUR.
I dont see that kraken x61 in our shops, but if the price difference is 70 USD and 212 Evo cost 150 PLN here, then kraken should cost nearly 500 PLN.
>>55618048
I don't see the problem
>>55618097
that is about correct, yes.
>not owning weird offbrand fans
Seriously, some of the best fans I've ever had. Right up there with noctua. They don't do well sitting horizontally, but most don't either.
>>55618335
Gelid are hardly a "weird offbrand" fampai. They're one of the bigger names in the cooling world, albeit more for things like aftermarket graphics card coolers and thermal paste than fans specifically.
>>55617550
>tfw noctua costs 25€ in Sweden
>>55619424
Their warranty though is superb.
>>55615555

>>55618097
Go for SilentiumPC products, Fortis 3 or Grandis. 212 EVO at its price in Poland is a meme.
>>55619661
They only achieve performance through sheer RPM. Plus they barely control temps on what I need them to.
I have a serious question. Why would anyone who is buying a fan not just go to corsairs website and buy a replacement fan from their 'accessories' page instead of one of their $7 fans that they and other retailers sell? They are just as good and like half the price.
Question im gonna upgrade from an 8320 to a i5 6600k. Should I get a kraken water cooling radiator. I've got a thermaltake v71 full case. My gpu is a fury x. I live in Miami and it's hot as balls always.
>>55620413
I plan to oc as well. My current 8320 is at 4.6 with a cooler master nigga rig shit i did. Pic related.

Thinking of this mini itx case how is AIO or a big noctua block on it?
>>55620453
why the fuck is it ziptied a 212 evo comes with extra brackets for another fan you know?
![h115i_02[1].png](https://i.imgur.com/YTQegFh.png "h115i_02[1].png")
Currently using the H115i configured in push-pull as intake. I know /g/ sometimes shit itself for having a rad as intake, but what the fuck do you want me to do? The choices are either blowing warm air into the case or cooling your rad with warm air from the case.
Would highly recommend anyway. The Corsair Link software is a little derpy but functional as needed.
![P1030749[1].jpg](https://i.imgur.com/G2VVZPT.jpg "P1030749[1].jpg")
>>55614604
I have a question:
I'm getting a new mini ITX case in the next few days with a closed GPU partition, which has its own fan system (right side in pic). Is having a second fan directly over the card (which already has two) useful or actually a detriment? To me it seems it would inhibit proper air flow but would appreciate opinions.
>>55621506
I have a H100i and using it as a intake blowing cool air to it actually doesn't improves temperatures at all and I have 3 fans on the front of my case blowing fresh air right into it beside thee stock fans.
Changing the fans profile to performance barely makes any difference not even 2ºC just a lot of noise, 2ºC won't even help you with temperatures at all.
You have to consider that closed loops have the temperature sensor on the CPU block where the pump is located too, so temperatures reported for the "unit" or "water" are actually just the temperatures on the piece of copper on the CPU block not the liquid inside the unit, once the liquid reaches the radiator temperatures drop by a big magnitude just by the bigger area, so having it as a intake or exhaust(blowing hot air to it) would barely make a difference, the real difference comes from the size of the radiator and the pump.
Closed loops are truly a meme.
>>55621506
If you blow the hot air out of your case, internal temps will actually be much cooler.

This might be a winner as goddamn that static pressure.
Any reason to go with a premium brand like noctua over these? Been running 4 of these in my pc for almost a year now and they've been great so far
>>55620834
that thing is noisy as fuck if anything is close to the intake side of the fan. It only works in very specific scenarios.
>>55624119
Most of these no-name fans have decent enough airflow but certainly nothing special. Though in noctua's specific case they have really, really long warranties available which is where part of the price goes. Off the top of my head their standard warranty is 6 years - virtually nobody else offers than on regular fans.
In my experience, Delta Electronics makes some of the most reliable and powerful fans thet you can get for a decent price. Super easy to re-oil the bearings and make them operate at peak efficiency.
>>55624277
A lot of the fans they make require a lot of power - far more than what most headers will provide.
>>55623685
That doesn't really address the concern here though. You can have other fans blowing hot air out of the case. The rad fans don't necessarily have to be exhaust as most people seem to think.
>>55621966 is pretty on point here.
>>55624289
true
lol at all these retards itt who spent hundreds of dollars on giant fucking coolers and noisy closed loops when they could have spent $45 on a thermalright ts140 and gotten the same results
>>55624384
i spend 55aud on my seidon 120v plus
I have a Rosewill RSV-L4000 with three stock 120mm fans and two of their four bay hot swap HDD cages. Both the cages have 120mm fans blowing right into the case fans.
I have two questions. One, can I just get rid of the cage fans? They seem to be redundant.
Two, if I want to replace the case fans, can I just get any PWM fan and plug it into the motherboard? My motherboard supports it, but there are a few Noctua fans and I'm not sure what the best fit would be.
>>55616427
>got an idea
Son, take your 192x192 fan and tilt it such that the hypotenuse on pitch equals your micro expanded dong.
This way, from the outside, the fan will look to be 4:3, but it's just trickery of trigonometry.
