How much should a CPU run at and what are its limits?

Mines a Dual Core Pentium and my tower has three fans, but its still hitting an average of 57ºC, what can i do to reduce this?
You are free to do what we tell you.

Get a better heatsink.

Although 57 degrees isnt killer, I do advise getting one.

My computer runs at -273 degrees celcius, that way I have an infinite source of energy for wolrd domination.

57 is nothing dude... My CPU temp is at 65ish and my GPU is at 77ish.


That doesn't make it right...

Personally I'd say idling at anything more than 45-50 is a bit dodgy, give your fans a clean and re-seat your heatsink with some new thermal compound.

If you don't know what I'm talking about then google it.

Check your fans are working correctly, no dust or anything in them. Check your connections to the processors and everything, and see if you can't get a liquid cooling system installed. Failing that, a simple USB desk fan should suffice.

Also, if your tower in a pretty compacted space? like pressed right against a wall and against a desk or something similar on the floor? If so, just put it in a more ventilated space. If it's closed up, the fans aren't really doing anything, just trapping the hot air and moving it around inside...

Blackrat has won this thread. That is an awsome post.


This was posted right after I posted said post in a completely different thread... Whups.

Liquid cooling is only really necessary if you're doing heavy overclocking; my CPU is slightly OC'd and my air cooler holds up just fine.

I know what your talking about. But meh... I'd rather just call dell and get a new one for free ...

You see, I can do that because I bought 'accidental damage support'.

Different CPUs have different maxes.

Here's an example AMD one. Don't just trust one place though, check out some other lists

Maximum =/= good operating temperature. Running your components hotter will shorten their lifespan so it's in your best interests to keep temperatures down.

Best place for these type of questions is the Hexus forums.

Ideally, you should acquire a decent heatsink, like a an Arctic Square Pro or Tower, that uses heat pipes and built in fan.

With the new heat sink, you should "lap" the bottom of it that will sit against the CPU.

The reason you do this, is because not all heat sinks are made equal. The bottom will usually be nickle plated copper but may not be truly flat. It may be concave or convex, in which case, not all of it will contact the CPU and so more Thermal paste will be required. This is bad.



This image shows the impression left by my new Arctic Square Pro, in the Thermal Paste after initial installation.

As you can see, only a 1/4 of the heat sink actually touched the CPU. I was idling at 55c on a Core 2 2.14Ghz CPU. Bad

This was actually caused by the heat pipes catching on part of the bracket that wasn't needed, so I cut it off and lapped the bottom of the heat sink...I also lapped the top of the CPU.

Now it runs at 27C idle overclocked to 3Ghz.



To lap the heat sink, you will need a sheet of thick ish glass (I used a shelf from a TV stand) some 400, 800, 1000 and 2000 grit wet and dry paper.

Put the paper on the glass and stick it down. Wet it. Draw squiggles on the bottom of the heat sink with a Sharpie.

Keeping the heat sink flat, move it in a figure 8 pattern on the wet paper.

After a minute or so (maybe less) look at the bottom. You should see the areas without squiggles, is where the heat sink is contacting the paper. If it is just around the edges, it is concave, if it is around the middle it is convex.

Re-apply squiggles as required and keep going on the 400 grit until the squiggles disappear uniformly. Then move up through the grits.

When you are done, polish it up and it should look like a nice copper mirror.

You want the bare minimum of thermal paste on there. All you want it to do, is fill the microscopic gaps. Use Arctic Silver 5. A bit about the size of a grain of rice, in the middle on the CPU. Stretch a bit of plastic bag over your finger and work it around the CPU till it is covered.

Fit it all up. Temperatures will decrease once the thermal paste has settled in.

Just jamming in a lot of fans isn't going to make it cooler.

Make sure you have a proper airflow(on low front of the computer intake, and on high back outtake)

if you align them against each other things will only get worse
