Hi all... a few days ago I received a PC that I bought on eBay - a Dell Optiplex 7020 SFF Desktop PC 3.6GHz Core i7-4790 8GB DDR3 ram with no HDD. Upon receiving, I installed Win 7 Home Premium 64-bit and added another 8gb RAM and a 128GB SSD drive.
I got this machine to mainly run trading system backtests (lots of number crunching, lots of continuous hours use) so as soon as I got everything up and operational, I gave it a whirl. The CPU heated up to around 95C while doing a backtest and the fan was going like a jet engine... didn't sound too good. In the Windows Power Settings screen, I backed off the Max Processor Utilization from 100% to 99% and this dropped the CPU temp to around 89C/90C and quieted the fan down. Better, but still running pretty hot. Dropping the Max Processor Utilization % even more is an option, but this slows down the backtesting speed pretty significantly.
Ideally. I'd like to leave CPU usage at 100% and have a better cooling fan do the work of keeping the temps down. Would anyone be able to recommend a cost-effective cooling fan/heatsink for this PC that could do the job? I didn't pay a lot for this machine, so it really wouldn't make sense to pay a whole lot for a super-duper cooler... just something a little better than what's in there now (I'm assuming it's the stock Dell cooler) to bring the temp down a bit. This is my first experience with an "SFF" - there's not a lot of empty space inside the case, things are pretty crammed in there!
The full PC specs are:
- Win 7 Home Premium 64 bit
- Intel i7-4790 cpu
- Generic no-name el-cheapo 128gb SSD bought on temu.com
- 255W stock Dell PSU
- 16 gb DDR3 ram. 8gb already in there, added 1 8gb Corsair Vengeance stick.
Thank you everyone...
Shawn
