Default High Temps

I don't like the temps I am getting from my overclock. I have an E2140 @ 2.6GHz. The vcore is set to 1.35v in the BIOS and the new CPUz is showing 1.32v. My temps are 33C-35C at idle and 57C at 100% load. The room temperature is around 23C-24C.

My case is a Coolermaster CM690 that is close to the floor. I have an AC7 Pro, that contains either MX-1 or MX-2 paste pre-applied. Originally I had 3x120mm fans set to exhaust all the air and I figured this was the problem. So I took one of the 120mm exhaust fans and inverted it so it is an intake and I connected the front 120mm fan as an intake and added a 120mm fan at the back of the drive bays blowing air towards the CPU. My temps have not changed. In the BIOS my CPU temp shows 25C. Both Core Temp and Speed Fan show the same temps 33C-35C at idle and 57C at 100% load. Is there usually that much of a difference between the BIOS and temperature monitoring programs? Which temps would you trust. I have a funny feeling I'm going to have to reseat the AC7 Pro, which will have to wait until I order some AC MX-2 TIM. If I have to reseat the AC7 Pro, I want to clean off all the TIM and check to ensure the HSF base is flat and level. I may try and lap it.

Here is a diagram showing the airflow layout.

set both of your fans on the top to blow air INTO the case as this will help with cool air for the cpu and mosfets and etc around the area and allow proper air flow through the case.

I'm not real keen on that top "intake" fan idea.....

Looks to me like it's just going to recycle the hot air which would normally collect at the top of your case back down into the intake for your cpu cooler.

One thing I noticed when I had both fans on top as exhaust the air coming out was pretty cool.

as long as you have the fans on the front blowing properly and have a high enough cfm you'll have no probs.

They should be not sure what the CFM is on the two front fans. They are the ones that come with the Coolermaster CM690. The on 120mm Blue LED fan in the front and then a standard 120mm black case fan I have mounted at the end of the drive bays.

The fans that come with the case are good but not great. I suggest when you get a second to upgrade the fans to something more like the S-Flex ones.

Also take into consideration that the AC is not necessarily the best cooler for the job as when you have to crank the fan speed up it just makes more noise and doesn't really cool well anymore.

I have the AC7 running full speed and I was going to upgrade the fans. I want to get red LED fans. As for a CPU cooler I was thinking about the TRUE with an S-Flex fan or I might do water cooling, but I want to get the E7200 to replace the E2140. I have a lot of things to consider before I do upgrades.

I personally think your temps reflect the thermal limitations of AC7 Pro, investing in a True 120 or water cooling and you will defiantly see a reduction in temperatures.

I don't agree as I have seen others push the 2140 to 2.8-3.0 with an AC7 Pro and have lower load temps than 57C. However the fact that I have added 2 extra fans for a total of 5 120mm fans (3 intake, 2 exhaust) and the temps haven't changed would also lead me to believe that a) the limitations of the AC7 Pro. b) I need to reseat the AC7 Pro.
