Do fans turn hot into cold?

post #1 of 8
Thread Starter 
I have a set with a cooler master 212 plus and the fan is facing my gpu, and i was wondering if that the heat that rises from my gpu into my cpu turns cool because of the fan.

If that is all true then if i put a 40mm fan on my gpu wich would be intake to the gpu would there be pretty much no heat from my gpu getting into my cpu fan? Would they both be still able to get air into the cpu and gpu fan into the gpu.

I believe on your card the heat is expelled out the rear of the case. So there shouldn't be any of the heated air getting sucked up in to your CPU cooler.

I dont think i wrote this perfectly but the heat is coming off the backplate of the card not the side with the fan

I don't think there's enough coming off of there to really pose an issue quite honestly. and whatever may be coming off of there is probably being sucked out by the rear case fan.

But OOC, why are you asking? Temps bad or something?

No temps are fine, My gpu max temp is 55c because the fan is set to 100.
I just want better temps and to make sure my cpu is not being suffocated by hot air cause my case doesnt have great airflow.

You have a HAF!

What are your CPU temps under load?

Do you have an MSI afterburner cooling profile setup? No reason to run the fan @ 100% all the time. Not to mention it would be noisy.

No, warm air does not turn to cold air because of fans.

Heatsinks work like this:
Air is touching the heat spreaders (heatpipes and fins). The heat is transferred to the air which cools the spreaders which cools the CPU. The fans then move the warm air away and allow for new air in. If the new air is already warm, it isn't going to get as much heat transferred from the spreaders on the heatsink. I wouldn't worry that your GPU is pushing warm air into your CPU heatsink unless the temps of the CPU aren't what they should be. You case is an HAF, which stands for High Air Flow.
