Works really well

Excellent CPU Fan, replaced my old one and does much better. only problem is, my computer now sounds like a jet turbine on start up... it's NOT a quiet fan, but other than that, it's a fantastic buy.

Comment:
Running i&-860. Was running heatsink supplied by Intel and kept getting too hot. This fan dropped the temperature under load by 18 degreesC.

I recently just bought this heat sink for my i5 750. My cpu now idles at 25 degrees centigrade when it used to idle at 35-40. I recommend purchasing this heat sink if the currently owned case does provide enough room to house this monster.

I have used these CPU fans for two different computer builds and have found them to be excellent. They are easy to install, extremely quiet and reliable, definetly would reccomend.

This cooler is massive. It needs a back plate and is a monster to attach to the mobo. It works well enough and keeps the cpu cool and quiet, but it's so big that it covered my channel A memory slot. I could only put 4 gigs in my computer on channel B because of that. I don't know whether to blame the mobo for not giving enough space, the memory for sticking up too high, or the cooler for being too big. Luckily I only got 4gigs of memory and don't intend to get more.

This is a top of the line CPU cooler. Brought my Intel core 2 duo from 40 degrees Celsius idle to 19!! The fans are very quiet, even though of their size and the material from which they were made is also top quality. The case has to be removed to install it but that's the case with most CPU coolers that are worth the money. The unit is pretty big compared to the standard Intel coolers, but if it fit in my Asus P5QD, I'm pretty sure it will fit in most if not many of the motherboards out there. This CPU cooler will certainly stay around, even when i upgrade to an i5 or i7 system.

The cooler is large but fits nicely in most mid size cases. The intructions are simple and easy to understand and has plenty of pictures for those who don't read. It took all of one half an hour to remove the motherboard and replace the fan brackets and reassemble the computer. Talk about being quiet I had to look twice to make sure the fans were running. Great product

You really cant get any better than this. Only thing that tops it is liquid! my cpu is running a constant (16c)(61f). The only thing i would upgrade to is the Corsair CWCH50-1 Hydro H50 CPU Liquid Cooler. QUAD 5s Grade A

Dropped the temps on CPU with an added benefit. Also dropped voltage reg temp significantly.

This CPU Cooler brought my AMD Athlon64 x2 6000 temp from 51 idle to 33 degrees and 60 load to 41 degrees. I am happy with this cooler. Easy to install once you follow the directions. It is big but I have seen bigger. Great performance for the value.

This cooler keeps my unlocked Phenom II 550 overclocked 3.5ghz at 32-34c idle and 46-48c full load with prime 95. Tip:I used arctic silver 5 using the line method.

Comment:
took my Phenom from 60C to 30C.

Product is easy to install, gives good clearance to work aroud CPU and really cools extremely well keeps; my AMD Phenom II X4 940 Black, running at 100% is constantly kept at 44-46 degrees celsius.

Comment:
I am very happy with this cooler! I am running the Core 2 Quad Q8300 and it runs at very low temps! A must have for any compatible CPU!

Comment:
Great fan! Runs quieter than most single fan units. Put it on a AMD PII 965X4. Had to remove motherboard to install. Instructions skimpy, airflow is from right to left when reading the logo, install to blow toward back case fan. I just bought another one!

Comment:
The included Thermal Grease hardens up, in about an hour, so I will not be using that grease again. The Cooler works very well, the Air coming off it is very cool, even under Load. I'll be getting another one of these for an other computer I'm making. It is very quiet. does not sounds like a Vacuum Cleaner at all!

Comment:
FINALLY!!! I have just found the cooler that keeps my OC'ed i7 cool. Install was as simple as it gets. Dropped my temps from 60c idle to 33c and load from 90c to 55c. Just awesome! Just like some of the other reviews this puppy is HUGE but that is a good thing. Make sure that you orient the install to blow the heat out the back.

Comment:
Slapped this bad boy on my CPU after testing the temperatures on stock heat sink. This thing is amazing, it dropped my CPU from 50c down to 38c MAX load, it idles at 19c. What more can you ask for, does its purpose just perfectly!! Buy IT!!

Comment:
this thing rocks, AMD Phenom X4 9650 CPU has never gone over 27 degrees celcius, the fans push so much air is nuts

Comment:
Installed on top of a Intel i7 860 processor slightly overclocked. Temps never exceed 31 degrees Celcius. Quiet and it moves a lot of air. A little tricky installing on a Biostar TPower I55 mobo. I had to shim the back plate out a little with plastic washers so that the backing plate didn't rub on the tabs sticking out the back of the mobo for the electronic pieces on the front of the mobo. No issues with memory installation. This thing is big so you had better have a deep case. It really does keep the cpu cool. Excellent product and very well made.

Comment:
What a deal. My AMD Athlon 6000 has been plagued with overheating issues for a long time. I've tried many other CPU coolers and this unit did the trick. I used to average 65-75 C at idle & after installing this cooler I saw temp drops between 25-35 C. Take your time with the installation, directions were detailed, only took about 45mins from start to finish. Highly recommended!

It's a big honker though, but keeps my system cool and is fairly quiet. Installation is a bit tricky, Good performance for the money! You have to watch where you put your wires and fingers or the fan will let you know its there... The are no fan guards so be careful of your wire placement and especially your fingers..

Comment:
My i3-530 never goes above 40°C - 'nuff said.

She's a big ol honker, but keeps my i7 cool and is fairly quiet. Installation is a bit tricky, but what build or upgrade (besides ram) isn't? Good performance for the dough.
