Normal Computer Temps?

Are my temperatures ok?
The desktop is 5 years old.

The computer has been running all day.

I just finished cleaning the fans with a Q-tip (2 fans at the back of the case, one blows out, the other blows in... the other fan is pointed towards the CPU?), a Swiffer duster to lightly touch on everything else, a small hand held battery powered dustbuster to help suck up any dust in the crevices... which was useless because the battery died anways, lol, and the attachment to reach into small places was too big to get near the fan, lol.

 

The CPU temp seems a bit high to me. If it's idling at over 50c, then under a load it would probably run at over 70c which (IMO) is too high. If you have never cleaned/reapplied the CPU thermal compound, then it's past time to do so. 5 years is a long time to go. Thermal compound tends to 'dry out' and lose its effectiveness over time. You should probably remove the CPU heat sink, clean the old thermal grease from the CPU and from the base of the heat sink, and apply a new layer of some quality thermal snot. ArcticSilver is a quality brand of thermal goop and they have several different varieties, all of 'em are great. Just be sure to not use too much. While the CPU cooler is removed from the CPU, completely clean all the built up dust and debris by blowing it out with canned air or (preferably) an air compressor. Clean the fan blades (I use a paper towel moistened with Windex or 409) and the fan housing before applying the thermal poop and installing the cooler back on the CPU. If this doesn't lower your CPU temps by at least 15-20c then you might want to invest in a new cooler for your processor.
:-D

(on the other hand, some CPUs just naturally run hotter than others, and they can handle it )

 

I was mistaken, both fans at the back of the case blow outwards. Whew.

The computer was thrown together by a shop.
The cables inside are incredibly neat and tidy.
Yes, there's an Intel sticker on the CPU, I believe it's a Prescott from what I'm reading.
No room for another fan.

I thank you for all the installation instructions, unfortunately that's beyond my comfort zone.

I'm hoping to buy a new computer once Windows 7 comes out and start fresh... just hope this one lasts until then, or if I decide not to go with a new computer for a while.

Thanks guys!

 

The room temperature pretty much stays around 23-24C.
The case sits on top of a box, above the carpeted floor, in an open corner of the desk, slightly pulled out from the back and side of the desk. There's also a large hole for ventilation at the back of the desk. (There used to be an enclosure space but that was taken apart long ago to allow for more air flow).

Thanks!

 

I have 2 IBM 8090 series machines.P4 3.0GHz HT. Small Form Factor.
Both quickly get to 135F-145F within 10 minutes after startup.Have seen over 158F while under F@H load.
Normally running 24/7 with no problems.
