gpu,cpu vs. heat?

[bigbadwolf284]

just wondering if with a deacent water cooling on gpu/cpu , are u still cutting the life of the components short? if heat is the only factor here....or there are other factors...?

[gerrynicol]

Nope, whilst not prolonging the life of you components, it helps keep them going. Heat is a "stress" factor, along with voltage and high frequencies. To keep your system going, cooler is better and without any voltage or overclocking, better still.

there are points of diminishingly returns thow.. ??? something a lot of obsessive tweakers seem entirely unaware of.. he he he

If you're not running any components within specs then you're shorting the life PERIOD. It doesn't matter if you got that CPU at 25c at Load overclocked from 2GHz to 3GHz it will die sooner or later...no questions asked.....hehehe

[bigbadwolf284]

so whats the damage...heheh....any of u guys had a CPU dying on u.....?

[15th Warlock]

The damage is called electromigration, and it happens when a strong current or extreme heat causes the boundaries between the microscopic transistors inside any processor to very slowly melt away, until there's a short circuit inside the proc and it burns or it just dies...
It has never happened to me, and I've had a Pentium 166@200Mhz running for almost 10 years now and a Celeron 500@563Mhz running for about 7 years, I used both procs with stock cooling for heavy gaming back in the day (the pentium coupled to a voodoo 1 video card and the celeron to a TNT2 video card, both video cards heavily OC´d as well).
Now these procs spend their last days processing word and excel documents and accounting programs like peachtree at my dad's office, even the TNT2 video card still works :)
One word of advice though, stay away from volt modding, as it will very quickly take the life away from anything you OC, be it CPUs or GPUs, just don't do it, it isn't worthy IMHO.

"so whats the damage...heheh"

use your common sense and there wont be any.. increasing voltages too much is probably the biggest killer.. anything over say 10% could be considered too much.. anything over 70c might be considered a little hot..

stay within those limits and u are probably okay..

meh with my cooler I run a loop through the primary rad 3x120mm fan rad, then to the cpu then to the secondary rad dula 120mm fan rad, then to the gpu pump, res, and repeat.

works wonders to not have the cpu and gpu in the same loop, that way one doesn't overheat the other, and as for longevity, as long as the temps are still lower than stock and voltage isn't out of control you could be overclocking and still adding life to the cpu/gpu etc.

[bigbadwolf284]

about "glass systems" i wonder how long its gonna be till somebody actually gonna come up with one...lol
(or a wooden one) that would look good thought...... as soon i gonna get some $$ im gonna build one.....somebody have 2 do it.......(well it was done , but...they looked like Sh$%....)

yeah, I have to admit, heat may not be the ONLY factor, but it sure is a factor! running a 9800 "pro" on stock cooler at who-knows-how-hot made my card retire six months from purchase :( (I did replace the cooler with a VGA silencer about a month after softmod). I'm making sure to treat my X850 much better so it lasts longer...anyone know if 60*C VGA load is a good temp to keep it at? if its not I'll just get the ATIsilencer 5 now :D

[Thermopylae_480]

Is that idle or load. If its idle you better do something soon.

[yogurt_21]

60c load is fine, these gpu's can take more heat than the 9800's could, but I'd stay below 70.

[gerrynicol]

The whole thing about o/cing is don't do it if you don't have a good cooler, if you increase the heat, you shorten the lifespan!, that said it does not work in the other way decrease temp prolong lifespan.

The "key" to o/cing is balance. You need to find what will give you the best o/c without increasing the heat and voltage too much. If you can get a decent o/c and keep the temps the same, even better.

To be honest most third party coolers will/ should do a better job than the stock ones.

You have to think it further than just that.

What kind water cooling system you're talking here? Totally passive? If not passive is the radiator inside your case?

If you have whole system cooled by water (cpu, gpu, nb) and you have passive rad without fans, you have to pay attention to other components such as power circulation areas as well. Pretty much all new motherboards are designed in way that CPU fan also cools other mosfet and components near the power circulation area.

60c load is fine, these gpu's can take more heat than the 9800's could, but I'd stay below 70.

lol no problem! that would be 60*C MAX LOAD, so when I'm running ATItool artifact scan, thats the temps I get...after an hour or two of a good game like republic commandos, I usually see temps around 55*C.
