Your graphics card sucks up anywhere from 2-400 watts and has a tiny heatsink compared to the tower coolers and 1-200 watts a CPU would have. So why when I'm benching them do they both end up at 80 degrees anyway?
oyo?

die size, cooling area, density, parts active.
>>53728992
also heat transfer area.

Graphics cards are much larger and dissipate more heat

I'm curious how gigantic the Titan Z one is but I couldn't find any pics without the plastic bullshit.

intel cpus are ~90 watts at ~1.3volts, so they crank about 70amps at full throttle.
for reference, 30 amps will melt a paperclip.

You're not melting a fucking paper clip with 90 watts.

>1.3volts
It's not 1990 anymore gramps

yeah you can. it's pretty easy, actually, since the paperclip has a small surface area and can't dump it's heat very quickly.
Before CPUs had a thermal protection system in them you could burn them up pretty easily by popping off the heatsink while it was running. Some overclocking website did that to an Athlon, it reached over 300C within a minute without a heatsink (and was dead as a doornail afterwards, obviously)
>>53729233
Not him but it's like 1.2 to 1.4 on Intel's current shit.
>>53729224
here's 20 amps
>>53729064
Spacial gradients are irrelevant.
>>53729257
Some GPUs burn up with a heatsink.
>>53729333
And others burn up even with the heatsink on.

Amps means nothing to me without volts.
>>53729511
If your goal is running a current through a metal paperclip to melt it, the voltage is almost meaningless because of the low resistance of most metals. Like you could take 90W, transform it into 900A with 0.1V and just vaporize that paperclip in a split second.
coolers seem adequate for the tdp they are using

Why not use, like a 800rpm fan?
>>53730319
Why use a fan at all if passive works?
>>53730342
I never trust passive if I can help it.
A single 800 rpm fan added to that heatsink would massively drop temps and still won't make any noise
>>53729268
is it 20 amps at 0.5mV?
or 20 amps at 30kV?
the power it's dissipating is more important than just the amps passing through it
>>53730364
temperatures on that card are low even on full load, and there's no mechanical part that could fail (I had one or two broken GPU fans in the past)
>>53729636
Shit, never knew that.

Goddamn, has most of /g/ never even passed high school physics?
