YANCQ (Yet another novice cooling question)

Hey all --

Recently, I'd become concerned about the temp of machines of my home network (3 of em). I previously did not use A/C in my house; I do now, but my room probably still sits at about 80 (due to sunlight, second floor, etc.). I believe that my old Linksys switch may have died to due to heat problems. I've installed a Hardcano temp and fan speed monitoring device on one of my machines, which has helped keep the heat under control (and can alarm if it goes too high). Pic
However, my other machine actually runs hotter (more drives, smaller case, no case fan), and has just begun shutting itself off in the past week. The power switch on the back of the machine is automatically switched off. After resetting it, I can turn the machine back on immediately. This seems to be occurring at around ~51 C CPU temp (based on MBM). The case is at about 38 C. From what I've read in these forums, elsewhere online, and from AMD's own documentation, this should not be causing a problem.
The machine is running:
Board: Gigabyte Technology Co., Ltd. 7VKML 1.x
Bus Clock: 100 megahertz
BIOS: American Megatrends Inc. 07.00T 05/03/0102
1.20 gigahertz AMD Duron (no overclocking; "stock" heatsink and fan)

As I mentioned, it does not have any case fans. I currently have taken off the side panel, and have a room fan blowing in, and it has not shut off in several hours. This all leads me to believe that the problem must be cooling, right? So..... should I upgrade the HSF, install a case fan or two, or could something else be causing these problems? A faulty power supply, perhaps?

Thanks for any thoughts...!

you could also use an air duster to blow off any excess dust from hsf and any other parts.

How old is the PSU? I'd check to see if that's the cause of the problem since it could be overheating, shutting off and then let you turn it back on. Or you could have a short inside the PSU that's doing it. How old is the PSU? What size is it? What make/model is it?

All these questions and more answered on the next episode...

Well, the machine is actually only about 2 years old (custom built, with PSU that came with brand new ATX Mini-Tower case), so hopefully the power supply has not gone bad, but possible:
Antec Model PP-255XH 250W with "SmartPower"

Anything there sound suspect?

Alright, no love for my question. : (

How about this:
I am going to buy a new power supply and try that out. Should I go for a "name brand" on this purchase, or are there any other characteristics that I should look for in a PSU? Or, should I just go for the cheapest (they range from $15 to $60 for a 300W here)

Thank you,

Buy a high-quality unit. Quality first, and extra wattage is fine for cushion :) If your case uses a funky form-factor of power supply and not a standard ATX-type PSU, then you are going to be a hurting unit when you try to find a quality PSU in a weird formfactor. Hopefully your miniATX unit is replaceable with a full-ATX unit as is sometimes the case.
