CPU Cooling

I would fit an extractor in the top of the cupboard; you'll be able to pick up a computer fan at Maplins for small money. Is the heat actually affecting the processing speed?

Heat rises..so a fan at the top is a good start..

companies often have a cold room for servers etc

I would just move it out of the cupboard and get used to the whirring.

Sort the cupboard temps out. Cooling is all relative to the ambient temperatures. You can't cool below ambient without hideously expensive sub ambient cooling equipment.

Once you can control the cupboard temps with ventilation. Then check that your case is clean. Fans and heat sinks are free of dust etc.


Alternatively you could pull it out of the cupboard and look at water cooling. You will still have fans running for the radiators but at much lower rpm than traditional cooling.

I've just downloaded a temperature monitor for the CPU mines at 35c,
during hot weather it sometime makes a wurring sound too

My PC was as noisy as feck at times. Swapped the SATA disc drive for an SSD and it's been as quiet as a mouse ever since. This has led me to believe that the old disc drive was the main source of heat inside the box.

Have you ever seen the heat extractor around the chip in a laptop? It's a rather crude chunk of copper curled around the chip and leading out to a radiator.

[QUOTE 4470153, member: 9609"]I have plenty of old fans from older cases., and yes I was thinking blowing it out of the top would be better than blowing in the bottom (but don't know why)

I don't think it has been affect processing speed (not really sure though) but going over a 100c seems pretty excessive, I understand about 70 should be the max[/QUOTE]
Sucking hot air out is always going to be more efficient than blowing ambient air in, as for positioning as long as the vents are higher than the heat source they'll be fine.

My old Physics teacher would have chucked the blackboard rubber at you for those first two words.

Heat doesn't rise, but hot air does.

You might want to think about a separate graphics card, with it's own cooling, as you're probably overtaxing what is a fairly low end m/board

Back in the early 1990's we designed a server, it had 3 PSU's and we had all sorts of heat issues.
We resolved this by replacing the bottom with a tray of 8 x 4" fans and an offset grill at the top
It worked on the chimney venturi effect, and solved the heating issues instantly

It did however mean that the server bore more than a passing resemblance to a stove.

Isn't that defeating one of the main advantages of a laptop, always having to be sat next to a radiator?

Wouldn't be such a downside this morning. Chilly cycle to work. Would like to have been sat next to a radiator.

Closed loop water cooling can be got for £50. Very effective, but the cupboard will be even hotter.
