Q8400 overheating

post #1 of 17
Thread Starter 
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.

I think most people will say this, get the best thermal paste, (Arctic Silver 5)?
As for a cooler, I have no idea about your processor so hopefully someone else can inform you about that.

Just reset and replay, make sure the right amount is added etc etc. If you are OCing check setting, and run with something like prime95 for a new hours (many like 12+ hours) and make sure you are stable, it will also push your comp harder than any game will.

Thanks for the quick reply.

I didn't run Prime95 because even when idle, my temps are too high; with Prime95 it would only show values more than my an hour gaming temp (or am I wrong?). I saw no reason to push more since it is already extremely hot without any push.

I know the Thermal paste was of no high quality but since I don't think OCing I thought it was quite enough.

BTW, I forgot to mention I get the same results both on XP and W7.

Q8400? Your CPU-Z screenshot says Q9450. And by the way, those stock coolers that came with Q8xxx and up to Q9400, at least, was only half the size of the old stock coolers that came with 65nm CPU's.

Using my Q9400@stock with intel's stock cooler in a barebone case I too saw temps like this.

smile.gif Just noticed that. Very interesting probably I have a very old version of Cpu-z. In fact the cooler I am using is the cooler of my old c2d e4400. They are both lga 775. I didn't think they would change.

theese temps are nothing unusual with a stock cooler. some degrees are depending on TIM, seating, and airflow in the tower.. i suggest getting a better cooler for it.. or not biggrin.gif
post #7 of 17
A cooler of just about 30-40 will get you the temps you want. lucky you, you might even be able to get them at the store and not have to order it off line haha

You are running widows 7 64bit? you need to go into your C: drive, find the system32 folder and hold shift+delete and then hit yes to the message that comes up.

I actually had a customer PC in the other day that had a Q6600 on a stock cooler. I was running Prime95 on it because the machine would beep during games. But it hovered around 68-72C almost through the whole thing. Which really is just at the Intel spec for maximum temperature. Granted the 6600 runs a little hotter than a Q8400, but I would say 70C isn't horrible. It should still run fine.

I have a Q6600 at home on a Arctic Cooling with AC5 as a thermal compound. It never hits above 60C on load but at stock. And OC'd to 3.6, rarely gets above 76C on load with 1.5 vCore.

I would definitely invest some money in a nicer cooler and some good paste. Arctic Silver 5 is freaking awesome and don't use anything else. The place I work at does the same thing, AC5 all the way. A decent cooler and some paste on Newegg shouldn't run you anymore than $50.
