CPU Temps of up to 86c.

post #1 of 9
Thread Starter 
I'm not sure why but my CPU is getting pretty hot while playing games. I have the i7 3820 with the Asetek 510LC Liquid Cooling System 120MM Radiator & Fan; and it doesn't seem to be doing the job. My cpu is always around 48-50c on all cores while browsing the web, and then goes up to 70-80c while gaming. These temps don't look normal to me..

These temps are way too high. I'd check to see if you have applied TIM properly or if the cooler is properly seated.

How long have you had the system? What GPU do you have? What case and how is the airflow setup?

I've had the machine for around three months. I have 2 GTX 680'S in SLI. My case is the "Azza Genesis 9000" which has fans on the bottom that blow heat upwards to the top fan. My case also has two fans on the side ( for extra cooling)

this.

it sounds like you aren't using any TIM at all biggrin.gif or you have a busted water pump in your CLC

Where does CPU set? Top of motherboard or bottom?
Is everything clean, no dust collected on fans or cooler?

The CPU sets next to the top fan. (I believe it's the top of the motherboard.) I just cleaned off the dust like two-three weeks ago.

I ordered the PC from CyberPowerPC. I'm not 100% sure how they set everything up because I've only opened it a few times. Anyone else have experience with CyberPowerPC CPU heat problems?

Did you check behind the cooler fan? If there was dust on the cooler fan than there is probably dust and possibly worse behind it. As an example, a stock AMD cooler with fan removed:




Here's a basic tutorial about airflow and cooling: Warning: Spoiler! (Click to show)
There is much more to cooling than good cases and good CPU / GPU coolers. Modern GPU's make more heat than CPU... and getting that heat out of the case can be a challenge.

Setting up the case to cool properly is the hardest and most time consuming part of a build... And the most neglected by most builders.

Cases, especially those with filters, usually benefit from fans with higher static pressure ratings than stock fans... "cooler" fans instead of "case" fans.
Intakes are typically more restricted than exhaust; air filter, more restrictive grill, HDD cage, etc.
I prefer more intake than exhaust. And don't confuse number of fans with amount of airflow... or airflow with airblow

airflow is flowing cool air from intake to component and flowing hot air from component out of case without the hot air mixing with the cool air.

airblow is lots of fans blowing air with some of hot air from components mixing with cool air making it warmer resulting in warm air not cooling components as well as the cool air will.

Putting fans in case as intake and/or exhaust is only the first step. These fans only move air in and out of case.

This does not mean heated air is not mixing with cool air.

Nor does it mean cool air is going to where it is needed.

Getting the air to flow inside of case properly is even more important. We still need to manage where the air flows inside the case. We can do this several ways; deflectors, cooler intake fans, exhaust fans, removing vent grills, using fans with higher pressure/airflow, building ducts to or from CPU/GPU cooler, etc.

Using a remote temperature sensor to monitor what air temps are is the key to finding out where the cool air is flowing and knowing heated air is not mixing into it. By monitoring this we can than make changes to get airflow the way we want it.

I monitor the temps with a cheap indoor/outdoor wired remote or terrarium digital thermometer. Twist a piece of stiff insulated wire into the last 8" of sensor lead so you can bend it to position sensor where you want it... like 40mm in front of your GPU cooler/radiator intake.. to see what the air temp going into CPU / GPU cooler is compared to room temp. The closer it is to room temp the better.. Shouldn't be more 5c maximum, 2-3c is what I usually end up with after 30 minutes full load on both CPU and GPU. Warning: Spoiler! (Click to show)
