Computer/Case Cooling

Yes, the old chestnut of the computer running quite hot and the overheat alarm coming on.... anyway i've attached a little diagram of what is currently in the system.

The CPU HSF is the stock one that comes with the sempron processor, and the other two fans came with the case and are for quietness as well as coolness.

The two pci slots that aren't taken up have vented covers on them (pci slot covers with holes in).

So, is there any way i could improve the airflow/cooling of my system? its annoying when watching tv . there are about 16 power connectors left so plenty of room to put more fans in, i'm just not sure about whether there are specifics for airflow etc. Currently it's idling and the CPU is at 55C and the case at 50C, with the lid taken off....

Re: Computer/Case Cooling

From that diagram you'd be getting a serious amount of negative pressure ... I'd reverse the 60mm fan at least... my general principle is to try and match the input CFM with the output CFM.

Negative pressure makes the fan work harder and therefore creates more noise/vibration shortening it's useful lifespan.

If you can add another input fan that would be a start. The larger the better.

Re: Computer/Case Cooling

Its a strange style case, or its wrong orientation and im geting confused,

You really do have some negative pressure.. get some fans blowing some air in...

failing that .... take the side off (thats what i did till i got enough fans... (not the best for prolonging the life of your machine though).

no, its a strange design. It's a desktop HTPC style case ,the PSU is situated at the front of the case, next to the optical drives.

Anyway, i have since turned round the fans on the case (i got the measurements wrong, they are actually a 92mm rear exhaust and a 80mm side exhaust). The lid is sitting off too at the moment, bu i am sure you can appreciate that this looks damn ugly in the living room

temperatures are now hovering around 50-55C, so a slight improvement. i've disabled the annoying audible alarm too, so at least we can blow the cpu up in peace

[edit] oh and the PSU fan blows out of the side, rather than the front

Re: Computer/Case Cooling

I'd turn that 80mm fan around to make it an input rather than output fan.

Re: Computer/Case Cooling

Any improvement in temperatures?

If not I'd put the 92mm back on output.

Reverse your fans to suck air in, get a 120mm hole cutter and drill a big hole in the top of the case, attach a mammoth Vantec silent 120mm fan blowing air out and bob's your aunties live in shag piece.

Failing that a drill and patience I have my drives in fan cooled caddys and my PSU is double fanned, it's amazing how much heat you can kill just by getting a decent drive enclosure and PSU

AMD have some optimum airflow diagrams on their site:

Re: Computer/Case Cooling

Thanks for that mate, handy info for the rig I am building up now.

Just fitted a 80mm outtake on the back a 120mm intake on the side panel and 1 80mm intake on the front with a filter on my Siemens pc and the performance is nice so is the 29c Case temp and CPU temp of 39 and 49 under load.
