Q8400 Overheating

[mtolgae]

Hello. My rig first:

CPU: Intel q8400 @stock speed (2667) (Intel site Max temp is stated as 70 C)
Mobo: Gigabyte 965p DS3 Rev 3.3 (bios firmware F14) (all drivers installed and are up-to-date)
Ram:4 gb DDR2 800 ram (2x1 Veritech, 1x2 gb Kingston)
HDD: 1. ST3320620AS Barracuda 7200.10 SATA 320-GB
2. SAMSUNG EcoGreen F2 HD154UI 1.5TB
VGA: Gigabyte GTS 450 1gb @stock speed
PSU: Hiper 530W Black Type M PSU
Case: ASUS TA-951
Cooling: Glacial Tech 120mm in the back and a 90 mm coolermaster fan in the front of the case. Cpu has the stock intel cooler.
OS: Windows Xp Pro sp3 & Windows 7 x64 in another partition.
Room temp: 26 C

The problem:

I had this second hand q8400 recently. Before that I had a c2d e4400 @3000 Mhz without any problems at around 30 C idle. Ever since I installed the q8400 idle temp is around 45-50 C and load is incredibly around 70 C after an hour of gaming without ANY OC to any hardware.

I double checked my stock intel fan to see if I placed it right. I reinstalled the heat sink after cleaning it and applying a cheap thermal paste. It doesn't move, placed correctly.

I think the temp is way too high even for a stock cooler. Many people can push a q8400 over 3 ghz with stock cooler. So I don’t think it is all about the stock cooler. Case cooling also seems OK to me. You can see further details in attached pics. Thanks in advance for the help.

You could try re-setting the stock cooler by cleaning off the thermal interface compound with rubbing alcohol and applying some Arctic Silver 5. But, I think I would replace the stock cooler with a CoolerMaster Hyper 212+ (with Arctic Silver 5).

Did a bit search and here are the coolers that fit my price range and are available here (in Turkey):

XIGMATEK HDT-S963 - LGA775/1156 & AMD AM2
XIGMATEK LOKI SD963 - LGA775/1156/1366 & AM2/AM2+/AM3
XIGMATEK RED SCORPION S1283 - LGA775 & AM2
Cooler Master Hyper TX3 - LGA 775/1156 & AM2 / AM3
Sunbeam Core-Contact Freezer 92mm - LGA775 & AM2

I have intentionally wrote the cpu compatiblity in case of any future change of my cpu. I already know there are way better coolers around, however they are not either available here or much pricey (CM Hyper 212 plus is twice as expensive as the ones I wrote above for example). So if you were to choose one of these which one would you choose?

my Q6600 2.4 Ghz full load temp is around 55C with after market cooler. CPU fan is at 2000 RPM. So your temp is probably right because it is stock cooling with low RPM(1300)
