Heat problems

K6 450
ASUS P5 99VM
Minitower ATX minimal venting on the lower right and a hole wher the tower's speaker's should be.
Power supply directly above the processor which for some stupid reason blows warm air into the case and on to the processor.

I have done all proper troubleshooting i.e. cleaning, BIOS flash, checked the bus speed and multiplier settings. With no hood on the case and a household fan blowing on it the issue disappears.

I don't want to mod the case or start filling it up with fans as this is a trade-in that I'll pass on to charity. I looking for a cheap alternative if there is one.

Is there some way to reverse the polarity on the power supply's fan. Forget that I just asked that as I have just found out that the darn power supply is spot welded together! :confused: :mad: I would consider replacing the power supply but it's an odd ball shape from a now defunct manufacturer (DKT Computer). (Gee I wonder why?)

#1 why in the hell would you want to reverse the fan???

no number 2

have you tried reapplying thermal grease and cleaning the HS?

In answer to #2 yes. #1 doesn't deserve a response if you think about it.

Yes, for a while ther they thought it was best if the PS actually blew onto the cpu like that. And the best way to handle that was to open the PS and remove the screws and reverse the fan.

Know someone with a dremel tool?
Cut the spot welds. But watch what you are doing!!!
Particularly the flying sparks and such. They can short out a ps if they get inside.

Just to check (don't want to offend) but... You did pop the metal heatshield off the processor right? A lot of people don't/didn't with the k6-x processors, and if ya don't then a) using thermal paste is of no value and b) the heatsink is far less effective.

As for fans... Ya could maybe put a slot cooler fan in if ya got an unused slot. For the front if there's no place to mount a fan perhaps you could afix one to the case bottom (magnetic tape is one way to do this) near the front intake area (what ever area there is). Not the best, but if there are holes/slots in front the fan will draw "some" air in.

The heatshield? Are you presuming that there is a shim between the processor and heatsink or are you referring to the thin lid?(see attached image). It would appear I'm one of those people have never removed the lid - it doesn't appear to lift off. Ive got an old one here, its a spare and I don't really want to damage it, in case this system has a meltdown, experiementing on trying to remove the lid.

It's tough to tell from your jpg but I think the answer is yes: the "lid" is what I am referring to. The picture below shows it a little better...

That's the heat plate (or shield as I referred to it as). If you didn't remove it don't feel bad, most people didn't/don't (the plate was not realy intended to be removed by AMD). And many a person simply put thermal paste between it and the hetsink. But the cpu slug is under that (plate). With the plate in place there is no direct contact with the heatsink, so the heat transfer is not what it could be. In addition (as I said above) the effectiveness of thermal paste on the plate is little or none (in fact, it can even be negative).

The plate can be removed though without too much trouble really. I searched around and managed to find a link that explains how to remove it. The instructions can be found here (if interested).

Probably would be much easier and less frustrating to just swap cases on this...get a real cheap one from www.compgeeks.com but as I see you are in Canada I am not sure about shipping there....
