My desktop machine is a killer in terms of heat generated. It sits under my desk and absolutely ROASTS my legs.

I have a floor fan (around 12" diameter) pumping air out from under the desk but still it gets VERY hot under there ...

Is this something anyone else has struck? None of my other PCs have this issue but they are either slower or in more "open" areas.

This one isn't a rocket (1.8GHz, single core) so should not be an issue.

Should I just chuck in and get something else?

It's always been a hot box so maybe just a fault somewhere. Case fans etc seem are all OK, CPU and mb temperatures are not high. It just feels ... hot!

Sounds to me it may just be the airflow around your case? If your case fans are doing their jobs then there will be heated air being exhausted from the rear, and if it has nowhere to go due to your desk's design then you'll be feeling it. But if the system temps are ok then I'd say your PC is doing just fine, and you may want to look at making some changes to the desk.

Dust..... Having the computer on the floor, it's sucking up heaps of dust, blocking heatsinks making it a hottie.

I got filters on my computer, that I clean monthly, It really helps keep the inside working cooler and I hope longer.

My case has Three in fans (125mm, 2x80mm all filtered) and one out fan (80mm below the psu),
My theory was to have a positive pressure of filtered air inside the case to prevent dust getting in.

Agree 100%. The desk is in a corner and is pushed against the wall so no air flow (hence the 12" floor fan).

The box is doing it's job and sending the heat out but my concern is HOW MUCH heat there is.

With the floor fan it's cool enough under the desk most of the time but still the whole room becomes quite hot compared to surrounding rooms.

Maybe you are right ... I might add a bit of space between desk and wall to let things circulate better.

Once again, agree with the filters but in this case the INSIDE of the case is AOK. The problem is just the sheer volumn of heat. The room next to this can be running the air-con at 21 degrees (and is freezing) but in my office next-door it still feels significant;y hotter if my PC is running (door open between them, of course).

Yes, air flow is an issue but is it just SOOOO hot.

I've been in this game for 20+ years and never seen an issue like this one.

Maybe I'll just replace / upgrade it ... and hope that the next box isn't even hotter!

have you run some software like speedfan or coretemp to get some tempreture readings? My machine has more fans than britney spears and keeps everything under 45c at all times.
