Intel Core i5 high idle temp
I just built a machine with an Intel i5-750 processor and it seems to be idling at a bit of a high temp...around 55°C. This machine was built for my uncle's business, and he had to have very specific measurements when it came to the computer case; it is housed in a cooler master elite RC-341 case. This is the only case that I could find that worked for what he needed.
Anyway, in my research I have found that the thermal specification for this processor is 72.7°C and I'm worried that if it's idling at 55°C in an open room with a controlled temp of 68°F, trouble is just around the corner when it's put in use at the office. Note: the machine is getting placed inside of a shelving unit enclosed on all sides except the front. Stupid! I know...but my uncle is hard headed.
So, to help with cooling matters, I installed a Corsair Hydro H50 liquid cooler on the CPU and have the front fan blowing out with the Corsair fan blowing in from the rear. Also, I have a side mounded 80mm fan on the case.
Is there anything else I can do to try and get this thing cooled down? Would it be worth wild to throw in the prepackaged CPU fan to see if it works better than the Corsair H50? Or is the small case going to be a huge factor either way? Any suggestions would be greatly appreciated! Thanks!

I reapplied new thermal paste, same results. CPU is idling around 55*C and jumps over 60*C when doing simple tasks. I'm using Everest and RealTemp to monitor temps.
I'm a little nervous to do a flash, as I've neve done one...what would be the proper procedure?

I might have found the problem...
After watching the Corsair H50 install video again, it was mentioned that some system fans will throttle the CPU fan header as needed for increased RPM's when the CPU reaches certain temps. He recommended that the header be set to "full power" for best performance of the liquid pump.
I went into the bios of the EVGA P55 V to try and adjust the settings, and I only found one fan control. It didn't give me the option to set it to full power, just to make it "accelerate" after a certain temp. I set it to do this if the temperature reached temps above 30°C to see if it made a difference. After restarting the machine, the back 120mm fan is at full throttle...not the pump!
Does anyone know if there is a way to adjust this for the CPU header fan on an EVGA P55 V SLI? I think that would solve the problem. Thanks again

Note: the liquid pump has a 3 pin plug, and the case fan it comes with is a 4 pin plug. Those are the only available headers on this board as well.

Calandor: the pump and fan both run continuously, or at least they should. The fan is nothing more than a 120mm blowing air in over the radiator. I emailed EVGA about the throttling of the CPU header, but I got a very short response that just said that the header is always on and can't be adjusted. Nothing about throttling. I might try to hook the fan up to a molex and see what happens.
ASKER
Callandor: That was it...the pump wasn't receiving enough power to run. I added a molex connector to the end of the pump plug, connected it, and voila...CPU temp reading 20°C!!!

Thanks for all the help guys.
DanMerk: Your article gave me some great benchmarks to go by.
Crzyivan0000: The flash might have worked, as i noticed a lot of the EVGA boards had upgrades for better fan control. All except the P55V, lol
Callandor: Your solution hit the nail right on the head. As soon as I had the pump hooked up to a molex, I could hear the pump pushing the water through the pipes. EVGA got it wrong when they said CPU header is always on and on full power...it is obviously a throttled header.
I learned a lot on this one, thanks for all of your contributions! Much appreciation!
