HSF toasted my MB?

I recently purchased a Thermaltake Silent Boost HSF to replace my noisy Volcano 6cu+. Little did I know what I would have in store for me.

I began by taking off the old HSF and cleaned up the ASIII on the CPU because I was going to put on the new Ceramique. I cleaned up as much dust in the case I could. I also took the HSF off my video card and cleaned the stock thermal grease off of it and applied some Ceramique to it as well as cleaning the fan with damp cotton swabs. After putting Ceramique on the CPU I put the Silent Boost on with no problems and put everything back in its place, leaving the side of the PC open. I plugged the PC back and pressed the power button.

Boom! In about two seconds I saw smoke emanating from somewhere and smelt the oder of disaster. I immediatly turned off the power and inspected the components. Everything looked just fine. Nothing was burnt or appeared damaged. To be safe I diconnected everything (drives, case fans, cards) except my primary hard drive and my video card and memory. I pressed the power button and would get power for about 4 seconds before it would just turn off.

Thinking I may have blown the video card I swapped in a older one and got the same results. Disconnected the hard drive, same results. Swapped out the power supply, same results. Eventually I took out the Silent Boost and put the 6cu+ back in with no grease. This time I got sustained power, but a steady beeping from the case speaker. I finally figured out that I could only stop the beaping if I used one stick of memory at a time (have 3, all of them worked). The computer would now at least try and boot up, but Windows XP would not boot. To be thourough I put the Silent Boost back in with no grease and once again, I could only get power for about 4 seconds then it would turn off. I ended up buying a new MB since everything else seemed perfectly fine. Everything is running back to normal now with the new MB, but I would really like the new HSF in since it is so much quieter. What I would like to know is if it is possible for a HSF to toast a MB? It was seated properly and did not appear to be contacting anything. I really do not know what it could have been. Any ideas?

Well I'm a bit rusty in the computer game, just one thought comes to mind, what did you use to power the new HSF? did you go directly off the motherboard 3 pin header, or did you use an adapter and get power through the power supply? Really the only thing I can think of off the top of my head.

Sorry for the response delay. I tried both ways. Initially I used the 3 pin header. Then I tried the adapter. Either way it still won't boot with the new HSF.

You never said what the new heatsink was doing during the time there was all the smoke...did it turn on? If it didn't it may have some internal short and that would be a great explanation for what you saw.

I wouldn't recomend plugging it in to anything you want to keep until you can verify if it has an internal short.

If it does have a short then it is deffective and would need to be fixed or replaced before you can use it safely.

The fan came on fine. I don't think it was a short. I got really brave the other night and hooked it up on the new MB. It worked flawlessly. My PC runs about 3 to 4 degrees cooler than it did before. Idles around 44, maxes at about 49. I'm still not sure what caused the "explosion", but it may have been a lost memory heat spreader clamp. I doubt even this though. What I would like to do is give my MB to someone who has extra parts and see if I can't figure out exactly what the problem is.

I used a 97% isopropyl alchohol solution and cotton swabs.

I think the 'Boom' burn something on motherboard that use to reduce noise(EMI), and the Silent Boost generate more noise the old one.
Ha ha ha! You bought a silent noisy HSF:)
