In order to mount this HSF to a motherboard correctly, you must first remove the fan, and then the fan mount. only then can you access the mounting clips for the heatsink.

while it works acceptably well, I wouldn't buy another.

As a previous reviewer said, you need to remove the fan to install it right. I did not believe first and struggled to do the "easy" way. After 15 minutes of frustration, I finally removed the fan and it was secured in 60 seconds.

Thermaltake was a brand I held in high esteem. So when it came to buying a CPU fan for my computer, I did not think twice about purchasing the TR2 M21. Well the first one I purchased lasted about 8 months. Then the fan seized over the weekend and I found myself looking for another fan locally. The selection around town was less than desirable. It was either buy another TR2 M21 or spend $80+. (Hindsight is always 20/20) But I went against my better judgment and purchased another TR2. That was only 5 months ago. Now I am in the market for yet another CPU fan, as my current TR2 suffered the same fate as the first.

It is possible Thermaltake's higher end equipment is better quality. However from my experience, I would strong discourage anyone from purchasing this CPU fan.

I installed this heat sink on my core two duo 2.8GHz about 4.5 years ago. It has been running almost continuously since then. Pulling fresh air directly from a side vent on the case with a duct directly above it, this CPU cooler has always kept my CPU cool. The only drawback is that after all this time of operation, the fan is wearing out and now has a rattle on cold startup, but all in all, this product exceeded my expectations.

I have two P4 machines, socket 775 and one Celeron D machine, same socket. When I needed a new cooler for one of my P4 machines I took the one from the Celeron and attached it so the P4 could keep running imeadiately.

I then ordered this one for the celeron, and it doesn't fit, not even close.

The copper is round, meaning that on either my P4 or Celeron machines only about 80% of the square proccessor surface area would be in direct contact.

Also, the Unit is square, all three of my socket 775 machines require rectangular mounting.

I don't know what this fits, but of my three socket 775 mother boards, none of the above.

Bought the first fan when I build my system and it lasted over 3 years, but then failed. Decided to go with the same cpu fan sense Thermaltake had a decent rep. That one lasted just over 4 months then started to rattle and shake. Thought it might just be a lemon so ordered another one from Amazon but this one only lasted about 5 weeks.(just out of the warrenty/return). So now Im back but trying a different brand. Would not recommend this item.

I bought one for a new pc I was assembling and it worked well for a year. It then started vibrating and making noise like the case would come apart. Thought maybe I'd gotten a lemon and bought another of the same type. It lasted about two months before the bearings started going out and vibrating once again! Does this thing have plastic bushings? Junk!!!

I can't speak to how this fan works because I never got that far. I realized after I installed it that I needed a 4-pin connecter instead of a 3-pin one. OK, that's my fault. But how is it that the negative reviews here on Amazon are more informative about how to uninstall this fan than anything that comes with the product? The box has a picture on it that's full of arrows and completely undecipherable -- do they tell us what to do with the push pins or show us the direction of the airflow? Not a single word. On the inside of the box or out. Not on their website either. Just pictures.

Except for their brilliant marketing approach - it's tooless! Oy yay! Because goodness knows that those of us who are buying CPU fans to install ourselves are averse to using tools. And words. Thermaltake has us pegged.
