Question: I bought this product long ago and its great, but i was wondering, if the fan dies, which fan should i buy to remplace it? keeping the V8?
Document: It did take 10 days. That is a long time but I was able to use the V8. I am certain it will cool even better now. So with a product that does as advertised and then some imho I think they have gained yet another loyal customer. I will be back when it goes to it's new home. It is now running around 27 at idle and 34 when i am browsing. i haven't checked it when gaming.
The warranty is 2 years (which I think is reasonable) so I had to buy a new fan, which is about $11.00. Installing the new fan is likewise a pain, and even harder than originally installing the cooler). It is a Cooler Master fan recommended for the V8. Nevertheless, I think that I might have installed the fan backwards. Even if I did install it backwards, it works great.
The very reason I bought one this large to begin with. I've had one CPU disintegrate when the cooling fan died on my years ago...different computer.
It is using the push pull push pull of two fan. The 120mm fan in the middle with an extra 120mm fan on the RAM side of the heat-sink has done wonders. I have learned a lesson in neglect and a dm good cooler. Yeah the old heat sink probably stopped breathing, due to dust, too long ago and the thermal paste was past it's prime. This is showing me what taking care of my computer and purchasing aftermarket, well designed, parts can do.
Not only does this CPU Heatsink look awesome its definitely got the performance of a V8! Hahaha yea this is a great buy! The highest temp I could get my CPU to was 41C/106F while gaming, and idles as low as 32C/90F. Easy to install don't let its look intimidate you hahaha. It is HUGE.
That one works very well, and hopefully it will last a long time. It keeps the temperature in my computer quite low, though with three large fans and one small fan this fan doesn't need to do much work. It's also very quiet; I tried using the Intel fan that came with the CPU I bought and it was so LOUD! I don't hear this one at all, though that's probably because of the three large fans on the case.
The V8 is cooling an overclocked AMD Phenom II x3 Triple Core, overclocked at ~3.6 ghz with the fourth core unlocked. At minimum, my idle temps were ~45C and stress temps hit a maximum of 65C at once. At the maximum rpm settings, the idle temp was ~39 with a stress hitting a maximum of 61C.I got a great deal off of my V8, and bought it for $[...] with free shipping from [...].
I bouth this item because I have a machine with a very small fan and It's doing a lot noise and I buy this for fix itGood Product!! !
HI, I order it on 3rd received on 9th swift as I live in England, Cooler is just great. It keeping my AMD3+ 3.1 on 12C ( 52F) and I try the stress on 100% load by prime 95 and temp kept on lovest fan on 39C (106F) and cooler master is silent, during 35 min test. Then for 10 min I turn it on max fan  it went down to 36C  (96F).
I replaced the stock fan/heatsink for my AMD Phenom II, and this Cooler Master V8 is much more quieter and offers better cooling temperatures. For the price, it's a great upgrade to make.The only bad thing about this is that it doesn't fit into my rig all the way, my sidewall was 2 inches short, but everything still functions fine, so it's no big deal.
Answer: I replaced the fan with a '' 120mm cooler master fan''.  I think almost any 120mm fan will work but do yourself a favor and buy a '' 120mm COOLERMASTER'' fan.  You can also do what I did and use an led fan to make your heats ink look cooler(.... master hehe)
