class just classthis cooler is very good has pused my cpu temp down by 20 at normal rate very please instrutions where abit hard to follow but a video clip on youtube soon solved that problem.24/08/2011

First Foray Into Water CoolingThis is the first time I have gone for watercooling. I was looking for a simple solution that mounted easily and simply inside the case and this is probably as easy as it gets. No assembly required, simply attach the fan and radiator to the case, add the mounting bracket round the CPU, and then attach the cooler block.
Apart from having to move the top on my Zalman ZZ9, as it obscured the radiator, the unit fitted without a problem.
My only criticism is that it is slightly noiser than I would have hoped, but having come from passive cooling this is probably to be expected.
NOTE: The unit fits on 1155 CPUs but the supplied docs haven't been updated, so use the 1156 instructions.

    Cool!Fitted this to a X4 965 and added another fan to the radiator for a pull push. My case isn't even great for sucking out heat but with this cooler the cpu idles at 25 degrees with a max of 38. Can't fault it.133 User found this Review usefullHelpful Review? Yes

    Shiny!My first aftermarket cooler. After a bit of frantic head-scratching on my part during installation (I accidentally bent a pin in the CPU socket!), my I7 950 is now running 30 degrees cooler (from 80 to 50C) when running the "IntelBurnTest" util. I would actually give 4.5 stars if I could because it looks like Asetek (who actually made this) have cheaped out on the plastic mounting clips; mine cracked under barely any pressure but still seem to work. Anyway, it looks awesome, and is so much quieter than the stock cooler it's just silly. :)131 User found this Review usefullHelpful Review? Yes

    Easy to install and Fantastic coolinOrdered this yesterday and I had it installed and running at lunch time today =)

    Installation was quite easy, installed it on an AM2+ board. No matter what board you have, you will need to remove it to isntall the backplate so keep that inmind! Just follow the instructions, they are pretty good.

    Once I turned it on I had to check that the fan was actually spinning! its that quiet! I booted up Bad Company 2 and played for 4 hours (max settings) and when I checked the temps it was 39c.....thats amazing as before I was at 55!

    The main thing to keep inmind is that all that heat is being vented straight out the case, so the mobo temps + gfx temps all go down.

    I cant recommend this enough, and for 50 its an absolute steal.

    p.s. I've compared this to the corsair one and this is ...cheaper...more uptodate...and the difference in temps will maybe be couple degrees.129 User found this Review usefullHelpful Review? Yes

    New InstallBought this with my first upgrade in about 3 years!! First step into water cooling, couldn't have been easier!

    Took 5 mins to install onto my Asus MB, on top of my X6 2.8 Phenom. Quiet as a mouse, in fact too quiet as I can now hear my HDD, need to invest in a SSD!

    Temps after a few hours of standard runing, extracting, some video editing are between 22c and 23c on each of the six cores! Excellent purchase!122 User found this Review usefullHelpful Review? Yes

    Great CoolerTemperature drop is significant from my old air Cooler Master. Plus with a pleasant tweek in my overclocking I managed an additional 0.4ghz overclock on my cpu. Unfortunately I had to remove my motherboard to install but other than that an easy instal. Lokks great with so much more space within the case. Note: add an additional fan on the radiator for increased cooling.118 User found this Review usefullHelpful Review? Yes

    worth the moneythe instructions were not very helpful but after noticing the very small socket numbers on the bracket and fiddling about with it i managed to get it installed onto my z77 board its nice and quiet i would defiantly recommend this to my friends and install it for them to save them time117 User found this Review usefullHelpful Review?

    Nice!Went from a Freezer pro 7 to this, massive difference on my q6600 b3 @ 1.5v, temps down from 67c to 52c when running prime95 for 1 hour. At stock clocks and volts, it runs 30c doing the same test.

    Happy!112 User found this Review usefullHelpful Review? Yes
