From the Manufacturer

Challenging a new generations of PC mod-ding, the Cooler Master V8 revs up ahead with its tough guard cooling engine. Superior in its design, this wicked-fun V8 monster has enough horsepower to out-perform its duties with any high-performance CPU while under the most critical heat conditions. On top of its stylish finish, the V8 Cooler has quite some rich features. For heat dissipation it is supported with it's smart 180W cooling solution. Modularized by 4 separate set of aluminium fins and linked by 8 diagonal up-rise heat pipes, the V8 structural design allows speedy heat transfer to a large heat dissipation surface. Another excellent key feature of the V8, is its precision fan control. The V8 is compatible with all current CPU sockets, and provides unsurpassed cooling performance. The V8 certainly is one of Cooler Master's innovative hallmark.

The Ultimate 180W Air Cooling Solution 4 separate modular sets of aluminum fins create a large heat dissipation surface for unsurpassed cooling performance 8 heat pipes maximize heat transfer Mirror-finished base makes for 100% contact with the processor   4 sets of modular aluminum fins 8 high performance heat pipes Mirror-finished base

Optimum Airflow The center mounted 120mm fan blows cool air through the fins of the heatsink and cools down the heatsink which is taking the heat away from the CPU smoothly

Precision Control and Quiet Operation at 17~21 dBA Adjustable PWM fan speed control, using a manual knob placed in the back of the chassis, enables fan adjustments from 7V to 12V, allowing users to find the perfect balance between cooling performance and noise level Main unit with PWM and Fan Speed Controller Fan Speed Controller is installed into PCI slot

Customer Reviews

Amazing is all I can say
When I got this Cooler, (Being in the big box that it is) I was very ecstatic knowing that it will solve my cooling problems. Now to be honest, this wasn't the ONLY product I bought to reach my goal. I paired this with a Cooler Master CM690 case that includes a front fan and a back fan (+ 2 fans for the top) for max airflow.

My situation was that I had a Micro-ATX case with a Quad Core, an 8800 GT (The hot hot GPU), two HDD's and a tv tuner smacked right close to the Graphics Card. You can imagine what kind of MESS it made. My temps were 63C on 8800 GT and 50C on the Quad Core, Which is a Phenom 9500. Ambient temperatures were near the 50's and all of it - ON IDLE! My comp shuts off without notice when playing games that use both the CPU and the GPU semi intensive to Intensive.

Now on to the Cooler; this cooler is HUGE. Not too heavy, but it's definitely big. The cooler that I had (Stock), could fit 6 times in this baby. It's only an inch away from the side panel, where I was planning to attach another fan but the performance of this cooler really brings no need for this.

I will say that it's a bit tricky to install. For you AMD users, you'll have to remove the existing retention bracket and install the one that comes with it, and also a supporter at the back of the motherboard. One thing's for sure - READ THE MANUAL. One thing they don't tell you is that you have to flip the Motherboard upside down while the cooler is in place to fasten the back supporter. Definitely tricky to install. I took an example from 3D GAME MAN on his youtube. Definitely helps if you need visual explanation. To top it off they added a nice red LED light inside.

The Results;

Previous Setup w/o V8
CPU IDLE 52 C
CPU LOAD 65 C
GPU IDLE 60 C
GPU LOAD 75 C

New Setup With V8
CPU IDLE 32 C
CPU LOAD 40 C
GPU IDLE 55 C
GPU LOAD 63 C

Conclusion; So this is on a fairly decent setup. My Phenom is OC'd to 2.6 Ghz and the temp budges a few degrees but not much. This type of cooler doesn't quite live up to its potential on this type of CPU, but I can assure you that dropping your CPU temperature by 20 Degrees does wonders in the overall ambient temperatures. WONDERS I say! This is because there's a point where the 8800 GT's fan starts to make a lot of noise. This is when it exceeds 65C. If you manage to keep it below this temperature, it won't make a noise. This is another bonus when dropping the ambient temperature and i'm glad I waited till Amazon got this baby back in stock, it was worth the wait!

Cool styling & even cooler temps
Bought this CPU cooler for a new build. It's sitting atop an Intel Core i7 920. With the CPU under load, core temps only reach into the low 40 celsius range. Cooler Master includes everything you need to bolt this guy on, whether you are Socket 775 or 1366.

Works ok.
Pros:
Keeps my i7 920 cool below 69 degrees C (realtemp.exe) under 100% load, Prime 95 stress test, 8 threads, maximum burn, 3 hours. Ambient temperature 78 F. The processor is overclocked to 3.41 ghz, stock voltages. I used Artic Silver 5, applied as per instructions on AS5 website, and a Cooler Master HAF 932. My mobo is an EVGA X58 the A1 variant, with Vista 64 SP1.

It looks good with the red led, and the "V8" logo. It is also very quiet even when the fan turned up to high.

Cons:
Frankly, I expected better cooling, reading the reviews here and on another site. But the problem with user reviews is you don't exactly know their test settings are, ie ambient temperature, case, motherboard, tim, and especially what "full load" or "load" means to them. And no, sorry, Crysis, Steam, and iTunes and an AIM client at the same time isn't full load (especially on the i7). You really need a synthetic like Prime 95 or Orthos to really burn it, for comparisons.

Of course this is my first i7, so I don't have any personal comparisons. But my E8400 ran much cooler 60 degrees max with the a TRUE and it was clocked at 3.8ghz. So maybe i7's just really run hot. Besides at 3.41 ghz I score a 40,000+ on 3dmark Vantage CPU score, which definitely must be a fluke since the top system globally is an i7 965 @ 4.4ghz with a cpu score of only 27,000+. But I've done it four times and I get the same score on average with standard deviation of less than 0.05%, so okay, I'll take it.

The installation was a bit tedious. It is probably best done with two people. And the screws on the stand-offs also needs to be turned counter-clockwise, something not exactly specified on the manual, which can be frustrating. Finally, the manual I received had the picture wrong. The unit has to be mounted with the V8 right side up with the case standing up, not upside down as shown, so the fan will blow from right to left, outside your case.

Other thoughts:
Cooler Master has the exact measurements on their website. So you can look at that if you're wondering if it will fit your case.

I am kinda wishing I had just bought another TRUE 120. But now I am saving for a Koolance liquid cooling system. I just want to beat 4.0 ghz, thats all.
