Cooler Master V8 Review

Cooler Master V8

Introduction


When we think of extreme cooling for computers, the first thing that jumps to mind is water cooling, phase change and other extremes like liquid nitrogen. Air cooling is old technology, not efficient and definitely not worth your while. That is very far from the truth as companies like Cooler Master has proven to us today. We asked and they delivered and man have they delivered.
Today we have for review the Cooler Master V8. It is a monster among air coolers and has proven to stand up next to almost all entry level water cooling attempts out there!


Packaging



As with our previous experiences with Cooler Master, they yet again failed to disappoint as the cooler came expertly packaged. They yet again demonstrated the need to make their shipping box tornado proof.



The small V8 box was swallowed whole by the shipping package and packed in with lots of brown paper fill. Great job as expected!



The product package was more than expected as it contained a wealth of information about what was contained inside.



Upon opening we came across a very sturdy clamshell with the cooler inside and all necessary instructions and hardware.







The instructions came in a multitude of languages again proving the scale and market that cooler master is targeting.

First Thoughts



This thing is huge and heavy! At over 800 grams it is not light but when one observes the construction and what goes into one of these, then you will instantly realize why.





It is built from a solid copper base featuring 8 heat pipes climbing up into 4 individual aluminum heat sinks with a powerful variable speed fan sandwiched in middle. This thing is so massive that I cannot fathom the sheer size of what the V10 or V12 models must be like.



After removing the label on the sink’s base, it was noted that more work could be done on surface preparation as although it was flat, it was not smoothed down to a shiny mirror surface indicating the presence of micro pits that could limit cooling performance.




There was definitely no lack of CPU hold downs as the box with included hardware was opened. Included was all necessary odds and ends like screws and thermal paste needed to get this cooler hooked up to your CPU and cooling in no time.




Assembly


Some minor assembly is required when using this heat sink. Included was all necessary hardware to hold this cooler down to any socket on the market today. The hold down bracket of your choice, dependant on your socket needs to be screwed into the top of the heat sink’s base.



You then screw in the hold down screws into the hold down brackets which you previously attached to the heat sink. The cooler then, after being placed on your CPU, must then be screwed down from the back of the motherboard using the backing plate needed for your socket choice and the supplied nuts and nut driver.




Performance


Test System:

Asus Maximus Extreme
4 gigabytes DDR3 Memory
Intel E8400 Core2Duo Processor
Sapphire ATI 3870X2 Video card
Cooler Master Ultimate 1200 Watt PSU
Thermaltake Xaser VI Full tower case
Cooler Master V8 CPU cooler


The Tests were all done at 22 degrees Celsius ambient temps and all temps shown in graphs are degrees Celsius. Temps were recorded at both Idle and full load using prime95 for 2 hours. Also comparison between high and low fan speeds was also tested.

Final Thoughts



This CPU cooler was very impressive. Even at a high over clock of 4 Ghz with notable voltage increase, it still kept the CPU temps on full load down to 49 degrees which is lower than the stock cooler at stock speeds on idle. This from my experience is as good a temp drop as would be expected from a good basic water cooling kit offered on the market today and with such over clocks achievable on air, it begs the question whether air cooling is really on its last legs or can companies such as cooler master with continued research and development, be able to bring us even more high efficient air cooling answers to the heat problem plaguing our computer systems today.




Overview


Packaging 10/10 frags: The packaging was way overkill for sure but it assured safe delivery.

Price 10/10 frags: With water cooling costing upwards of $200 and this cooler priced at $69.99 MSRP, this is definitely good value for money considering the performance it gives.

Design 10/10 frags: There is nothing like it out there… 8 heat pipes, 4 heat sinks in 1, fan speed controller built in. What more can anyone ask for?

Construction 9/10 frags: It was very well put together but my only concern was with the finish on the heat sink base. Lapping would definitely improve it and Cooler Master could put more effort into making the base a lot smoother.

Performance 10/10 frags: 4 Ghz on air with temps nowhere near danger levels for this CPU leaving lots of headroom for more. No more questions here on this cooler’s performance.

Ease of Use 8/10 frags: It is fairly easy but requires some assembly. Removing the motherboard always adds that bad taste in your mouth when installing a heat sink like this but due to the weight and the need for sufficient brackets, it is necessary.


Overall the Cooler Master v8 gets a score of 9.5 out of 10 frags giving it Clan Team Xtreme approval!

What were the voltages at 3Ghz and 4Ghz? It's hard to compare the temps per clock without volts. What TIM was used, and was it used on both the stock HSF and the V8?

I take it when you ask about TIM you mean the thermal compound. I used IC diamond thermal paste on both heat sinks and the voltage was up at 1.280V from the stock 1.125V during the 4 Ghz overclock. I just bumped it up to 4 and haven't tried going any higher yet just for the sole purpose of stressing out the cooler a bit more. I can't do that same overclock using the stock heat sink.

Yes, I was referring to the Thermal Interface Material. Thank you for the info.

[drizzt5]

It looks beast and your right about the price comparison between water cooling and this.

Any way you could test this cooler out with some quad cores?

[Duke-Nukem]

Wow! This CPU cooler in amazing! I am not an overclocker, but I would be willing to try it with this cooler. I had a AMD Opteron at work that constantly overheated from running CAD software. We water cooled it, but the pump died after 3 months. I was convinced that I did not want to try water cooling a CPU of my own, much less try overclocking it. With this cooler, I would be willing to "go for it" for my first time. You can't beat the price. Way to go Cooler Master, and great job on the review [cTx]BIGLIPZIT!

I have a V10 and i can tell you... its ridiculous. And i am running with a Quad.

Cant wait to be able to unleash the pics and results to the world

[Kevin Archibald]

How much case width do you need to fit one of these to have adequate cooling space between the top of the V8 and side panel? I was looking at the Lian Li Lan Cool PC-K10B ("Metal Boned K10"). NewEgg says the width is 8.3". I think someone had a V8 in an Antec 1200. The 1200 is 8.4" wide and side panel clearance was said to be tight. Thanks!

[knissel]

So would you say V8 > true for my i7?

[jmilo]

nice review...

The width between the top of the cooler and the side panel matters not when this cooler sucks air from one side and throws it out the other. The v8 is amazing and we are hoping the v10 is even better. We will have one of those reviews on the V10 up in the coming weeks. Now to go and say the V8 is better than the true, I do not have the authority to say so but we must thinki realisitically. The true comes with no fan and we are left with the dicision to throw an amazing fan on there. The V8 comes with a fan and that is the weak point since coolermaster aims are quiet operation and keeps fan speed from low to high being 800-2000rpm. To do a proper comparison I would have to rip the coolermaster fan out and use identical fans on the V8 and the True and put them up head to head then. We will see what happens in the coming weeks as thermaltake joins the battle and we will see which company can provide the best air cooling solution out there.

after seeing this i can definitely not wait to see how the v12 preforms

[systemviper]

Thanks for your effort, great info!

[Riggs]

after seeing this i can definitely not wait to see how the v12 preforms

That isn't even near production yet. V10 is next. Stay tuned guys!

[Russian]

I've already got the V10 installed and tested. Im just waiting for the official OK to release these pictures for you all to see.

I actually had the V8 for testing as well and its small in comparison with the V10 to be quite honest and the ram fan over the V10 really does keep your ram nice and cool. Its a great feature.

is there a great temperature difference with this V10?
