I recently built a new system based on the Intel Core i7 3820K. When I purchased the chip, the salesman informed me that the new intel chips no longer include a thermal solution of any kind. After telling him I was going to overclock my processor he recommended one of the ThermalTake Water 2.0 coolers, specifically the performer series (base model).
In order to get a baseline of how hot my processor runs at stock clock speed (3.6Ghz + 3.8Ghz Turbo Boost), I was looking for something to put my processor under high load for long time. A friend of mine recommended I use Stanford University's Folding@Home software.
I installed the software and let run for going on to 2 days now while using the computer for some light web research for school at the sametime. After being satisfied that the machine was stable, I decided to overclock the processor to 4.2Ghz via the motherboard tools. During this period of time the temperature rose about 5 degrees to 70 degrees celcius, the baseline was between 64 and 65. When I touched the radiator of my system last night it was very hot, maybe hot like a cup of fresh coffee.
My question is a bit of a multi parter.
First, is the amount of load being put on the system by Folding@Home equivilent to that which a high end game such as Skyrim may put on the system? Or would the amount of load be greater or lesser?
Second, Is Folding@Home considered a valid tool for testing a system against another system?
Third, I realize that the radiator is expelling heat from the CPU, but should the radiator be as hot as it is? With 2 fans blowing air through it shoudn't it be fairly cool?
