Temperature

[Taartje]

Hello everyone,

I have an Intel Core 2 Quad Q8200 CPU in my desktop PC, and I have been reading very odd temperatures since the day I got it.

At stock speeds, room temperature 19c (during the winter) the CPU reached temps of 71/6x/6x/6x with the stock cooler, so I decided to get a better heatsink: the Scythe Infinity Mugen with backplate.

My temperatures were below 60c when I had the heatsink seated. Still too high, but I was ok with it.

Now it is summer, and the room temperature is about 30c, the temperatures have reached 80/71/72/70 today during a burn test (!!). The Mugen is well seated, so that shouldn't be an issue.

Are my temperature sensors broken? Or can anyone tell me what is going on?

Thanks,

what program are you using to monitor the temps?

Speedfan,Realtemp,Coretemp and Everest, all same readings.

Is it the Scythe Infinity Mugen 2? If so, I would check my thermal compound. There is a poster over at techPowerup that has a 920 at 4.2 ghz with that cooler.

I also think it should be running cooler. This is a common topic for the Northern regions this time of year. (PS not a result of global warming)
Just some other points.

(1) For a Room temp of 19C you were still Hot at 60C. Your temp differential is about correct. That is if you were seeing 60s with a room temp of 19 C, then an increase in room temp of 10 C will result in an increase of 1.5 to 2 x that change (75 ->80). It is not a linear ratio as "warm" air has less cooling ability than "Cool" air.

So I gues my sensors are broken, is that possible?
Btw, my 9800GT is now showing idle temperatures of 55, which were its former load temperatures.

I think the problem is bad air flow. My Q6600 as idle temp of 55/55/52/22 and on normal gaming(any game) 65/65/65/65 and full load around 68 or69. Earlier due to bad air flow it touched 77 on full load. Maybe the problem is due to lack of airflow.

I don't think a PC should run on 71c with a room temperature of 19c, even with a crappy airflow.
I think it would touch around 90c with the stock cooler right now.
