Hello there,

I made this thread with the question if a CPU temp of around 70 (mine is now 65-67) is harmful / bad for the computer. On idle it doesn't drop but if gaming it only increases up to 69. And does this have any influence on my pc's performance?

CPU we are talking about
Spoiler (Click to View) Intel Core 2 Duo E6300

Thanks!

The lower the CPU the faster it will run,

70 degree's is quite alot mine runs at 35 with just fans, with water cooling you can get alot lower

Mine runs at 27 with XIGMATEK Dark Knight, besides I ave Antec Nine Hundred Two V3 Black Steel ATX Mid Tower.

70 degrees is hot for a CPU, and 60 degrees is VERY hot for idle. You should be seeing 35 degrees at idle. It's possible the fan on your CPU cooler has failed, or the thermal paste has failed, or the heat sink is not firmly attached to the chip. It could also just be large amounts of dust clogging things up and reducing the effectiveness of your fan and/or heatsink.

I would suggest carefully removing the side from your computer's case, and power it on and watch the CPU fan. Is it turning? Is it covered in dust?

If you see a lot of dust, turn the computer off (be sure to turn it off at the wall socket and the computer's Power Supply Unit too), then see if you can remove the fan from the cooler without detaching the heat sink. If you manage, you can take the fan away and use a vacuum cleaner to clean it. (Never vacuum the inside of your computer)
You can clean the heat sink by picking the large chunks of dust off with your fingers. Once the worst is off you can clean it using a dry cloth. Avoid using toilet paper or tissues as these can tear and leave remnants stuck on the blades of the heat sink. The best method of all is to use a can of compressed air, but personally I can never be bothered buying any.

While you are doing all this, check if the heat sink seems firmly attached, or if it is loose or wobbling at all. It should be attached so firmly that you can actually flex the motherboard slightly by pushing on the cooler.

If cleaning dust didn't work, or there wasn't much dust, and the cooler seems firmly attached to the board, you'll need to consider replacing the thermal paste and/or the cooler. The cheapest way would be to just replace the thermal paste. The best thermal paste is Arctic Silver 5. Once you have it, remove the entire heat sink and fan assembly from your CPU and carefully clean the thermal paste off both of them with a dry cloth. For your type of CPU, the best method is to apply a single vertical strip of Arctic Silver 5 to the CPU. Then place the heat sink back on top, gently wiggle side to side about 1 millimetre only, and secure it in place. For full instructions on the cleaning and reapplication process see this guide on Arctic Silver's website, which is specific to your CPU type:

If you decide to go for a new cooler, that will cost you a little bit more money, but in my opinion it's highly worthwhile. For your CPU, you aren't going to need a big cooler, so I would suggest perhaps the Arctic Cooling Freezer 13. That is practically silent, delivers stunning cooling performance, and costs very little.

Note that the cooler will come with thermal paste already applied, so you don't need to buy seperate thermal paste if you get this. You'll still need to clean the old stuff off your CPU though. Use a dry cloth. :>

@Annikk.exe that Arctic Cooling Freezer 13, it's bloody massive, wouldn't that insert stress on the motherboard due it's size and weight?

I would say you to clean the cpu fan and replace the pasta.

My laptop ran at 80 degrees most of the time and it eventually fried the components and caused it to crash so I'd watch out.

Nope, not at all. :> It works perfectly, I've used it in nearly a dozen builds. Reasonably easy to fit as well. :>

If you want to see a REALLY big cooler, check out the Nofan Icepipe. :P
