CPU fan replacement??
« on: October 01, 2001, 01:30:00 PM »
Hi there,

Since I figure I'm going to need a better CPU cooler I am assuming I'll need to remove the old one and want hints how to do that without breaking my new Tbird! I know there is "paste" of some type on the chip under the heatsink. How do I seperate them?


I currently have a 1.4gig AMD with a large gold anodized dual fan heatsink. The heatsink is rather bulky and probably has way too much solid mass and too little fin area. The fans are on each end and blow inward over the fins in a vertical mounting. There is no brand name on the fan so no other info there. Only way I can keep CPU from overheating is to have the case open and a fan blowing into it from the side.  :(

Well, all i would suggest is you run your system under load for awhile to heat it up and see if u can remove it once everything is hot, by hand...

Sounds like one of those POS Zalman HS.  Does it look kind of like a peacock's tail?

Nope it is roughly rectangular in shape with rounded edges. The fans sit in each end inside of the extended fins and blow inward. I think it's actually a good design except for one problem. There is too much solid material for the heat to migrate through before getting to the fins. If there wasn't so much solid mass it would likely be an outstanding device.

Hmm. I'm curious what case you are using?

Make sure all power to everything is OFF.

You will want to take the mobo out of the case before removing the cooler. You should then be able to simply release whatever clips are holding the cooler onto the CPU. It should come right off. There is a proper technique for each mounting arrangement, and you shouldn't have to use brute force. The paste will come off easily by wiping with a cloth or paper towel. Maybe a little alcohol. If it has a thermal pad, it will come off with a little scraping with a plastic putty knife and wipe with a little alcohol.

While doing this, check to see if maybe the thermal compound was applied wrong, or maybe the cooler was not installed properly in the first place, causing it to overheat. It happened to me once.

Also consider the possibility that the voltage was set too high on the CPU, or maybe your guy sold you an overclocked chip?

There probably isn't anything wrong with it, Mav. Adding more fans to the case is another option you might want to try. I did replace the fan that came with my TB MB. You have to take the MB out of the case, set it upon the MB protective foam (or a backup/leftover MB foam), push down on the fan to ease the tension on the clips and then lever the clips away from the CPU socket. I usually use a small screwdriver, but you want to be careful what you are prying on. Don't tear anything up!

I am using a case with front and rear fans. I have a HD Cooler device set into one device bay (three fans there), a fan on the system chip, cpu heatsink and fan, a fan within the power supply, and a directional cooler that has two fans on goosenecks that takes up a PCI/ISA slot. Thats ten fans! Once I power up the CPU might come up two degress and that's it!  :)

It's setup for overclocking, but I don't overclock.
