Windows 7: Best temperature ranges?

OK. From what I can make out, there are a few options:

1. The existing exhaust fan is not strong enough to draw sufficient fresh air into the case, or
2. The CPU cooler isn't seated properly, and can't cool the CPU down.

Can you removed the front cover (the black one with the "grill") and take a photo of the aluminium chassis behind it? I want to see if there is an option to add another fan.

I see.

But the problem is not the CPU, it's the mainboard, the CPU and HD are alway below 40șC. Their temperature is about 35șC. It's the mainbord that is always above 60șC.

OK. If you run the PC with the side panel removed, does it run much cooler?

The mainboard chipset is being passively cooled by those two heat-sinks you see on the motheboard. There can be two problems there

1. They may not have adequate cool air passing over them tho cool them off.
2. They may not be seated or properly bonded with thermal paste or tape to the chipsets.

Golden: The panel does not matter, it's always at the same temperature. The extra cooler gives me 2 degrees less. The extra fan doesn't give much either. I see that the important factor is the distance between the bottom cooler and the ground/table. If there is more distance between the case and the table/ground it gives me like 5-7 degrees less.

GeneO: One sink is the metal structure between the processor and the OEM cooler, right? The other is the one sitting next to it, right?

If it's so, then I guess you might be right: there were a lot of wires above them, and I think they only use thermal paste for the processor.

I'm going to tell that to the guys at the store were I bought the computer. I'll get back to you tomorrow.

Sounds like a plan. Good luck.

Hello again guys,


I took the computer to the store where I bought it and asked for a fix. They told me that this particular board has a design problem with sensors. First they took a look at the temp info provided by the BIOS, and then I noticed that the values there were different: the processor was running at 88-90 șC, that's to close to the boling point, but the processor does not feel cold if you touch it. They flashed the BIOS with the latest firmware and it fixed the problem partially: both Speccy and Speedfan reported temperatures ranging from 35 to 45 șC for the CPU, but the board coontinued to report 70-75 șC.

They changed the thermal paste in both the OEM cooler and the heatsink on the northbridge chipset, and added an extra fan. The overall temp decreased (according to the programs) except for the mainboard in Speccy and for something called Aux in Speedfan. Both temp values remained unchanged.

Now, seeing that all those changes (new firmware, corrected CPU values, thermal paste, and an extra fan) did nothing to the board temperature makes me think there is a problem with that other sensor. Besides, if everything is cooler now, and if it's all cool to the touch, it has to be a wrong reading, unless, of course, the high temperature reading comes from the PSU itself, since it's the only thing they didn't touch (and the program that ickymay suggested actually says Chassis temperature, not motherboard...).

Should I change the PSU just to see if anything changes?

Hi MR,

Sounds like you are getting somewhere. Can you remind us what make of PSU you have?

If your motherboard was at 72C it would shut down. My board is always around 30-38, and I believe 40-45 is the max (I maybe wrong) it just sounds like a malfunctioning sensor or a badly placed one.
