I have a new PC that is running far too hot (measured with CoreTemp) and would be grateful for some advice.
- Gigabyte P55A-UD4 Rev 1.0 Motherboard
- Intel Core i7 870 (LGA1156)
- 4x4GB 1333MHz OCZ DDR3 Dual-Channel RAM
- Sapphire ATI HD 5770 1GB
- Creative Labs X-Fi Titanium
- Corsair 650w PSU
At idle the cores run around the upper 40s degrees C! If I play Left4Dead2, the temps go to upper 60s! If I run OCCT Perestroika, it quits after less than 90secs of maxing the cores out as their temps touch 90!!!
The system is NOT overclocked and Turbo Mode is disabled, as is XMP.
Here's the case: http://www.overclockers.co.uk/showproduct.php?prodid=CA-002-XG&groupid=701&catid=7&subcat=1572
It contains one in-built 120mm fan sucking air in at front bottom and I have added two more 120mm fans - one venting out of the back below the PSU and one blowing in on the side. They are this type: http://www.overclockers.co.uk/showproduct.php?prodid=FG-001-FD&groupid=701&catid=57&subcat=4
I was rather expecting a more powerful current of air from these fans than there is - they seem rather gentle.
Also of note is that I used the stock heatsink and just its own pre-applied thermal paste (presuming that it would be supplied as suitably coolable out of the box when not being overclocked).
I have no spare parts for testing and will have to buy whatever is required. The question is where my problem lies. I intend to buy some thermal compound and re-do that manually first off but I can't imagine it will make enough difference.
Then I'm wondering about fancy heatsinks+fans and fancy cases:
Noctua NH-U12P SE2: http://www.overclockers.co.uk/showproduct.php?prodid=HS-010-NC&groupid=701&catid=57&subcat=1395
(this appears slightly too tall to fit in my current case.)
Antec 900: http://www.overclockers.co.uk/showproduct.php?prodid=CA-065-AN&groupid=701&catid=7&subcat=160
I don't want to splash out on one or the other or both unless I have to and unless it's definitely going to fix things.
Thank you in advance for your thoughts.
