Hey all. I think that I made a mistake. I just built a rig for my father-in-law and while formatting c to install Windows, the thermal sensor kicked in and shut 'er down. CPU (Athlon XP 1700+ with bundled cooler) was running 80C. The problem is that the case is a "Mini-Mid" and the power supply ends up about 1/2 inch from the CPU cooler==no clean, cool air. Is there an easy fix for this? The only two things I can think of are kinda radical

1. Dremel the steel side off the PSU, allowing air to be pulled in.

2. Cut a hole in the top of the case and put an intake fan right above the cooler.

If there's a better way, please let me know before I mangle this project!!! Thanx

Do it the dell way! Create a vent that channels air in.

Captain Obvious believes that your solutions are the most obvious!

Mini cases have inevitably have airflow and thus heat issues!

I have a BONUS solution! That's right, a BONUS solution! If this case accepts standard sized power supplies, <A HREF="http://www.newegg.com/app/viewProduct.asp?description=17-104-966&depa=1" target="_new">This Power Supply</A> is inexpensive, extremely high quality, and has a <A HREF="http://www.newegg.com/app/Showimage.asp?image=17-104-966-02.JPG/17-104-966-01.JPG/17-104-966-04.JPG/17-104-966-03.JPG" target="_new">HUGE 120mm EXHUAST FAN ON THE BOTTOM!</A>

Now, I understand that he might not NEED a power supply at this time, but you can always use his old one in another system!

I just finished an 1800 in the same style case. Temp = 37c. Make sure you put the hsf right way round. Try rotating it 180 degrees and see if it fits better.

I have a Shuttle PC and hardly ever have the cover on ;) LOL. I also managed to mod it a bit with extra fans. The unit is open, so I all I need to do is make the air around it make love to my heat-pipe cooler ;)

I noticed these small form factor boxes do not go well with heat. I also have an oc'ed GF4Ti4200 and I had to put a fan blowing air onto that - no space for a rainblower :(

Thanks for the suggestions. I know that I have the HSF mounted correctly and everything is right except that the PSU blocks the HSF. I know this because I was running 37C before I put the PSU inside the case and closed it up. The issue definitely lies in the power supply covering the HSF. Crashman, it just so happens I have your bonus solution in another rig and I'll be happy to swap PSU's to see if that helps. Otherwise there will be a "manually installed" intake in the top of this case (if not a new case all together). If anybody else has new ideas, I'm open to them.

Whatever you do, don't put a fan on the top of the case and have it blow air into the case. Hot air rises, so you would only be pushing the hot air back to the bottom of the case, making the innards even hotter. Now a fan on the top as an exhaust fan will help. It will take the hottest air at the top and vent it out, helping lower the temp.

Oh yeah, that would kinda defeat the purpose. The whole problem is that the fan has no air to push onto the heatsink. I am sure that the limited clearance of the PSU and the HSF is the issue and I need to figure out how to allow air to flow. BTW when the CPU was @ 80C, the Case Temp. was appx 38C. A little warm, but I don't think there should ever be a difference of 40+ degrees in these two figures.
