Eight Low-Profile CPU Coolers For Your Compact PC, Reviewed

Janus Installation

Screws from the assembled Janus cooler and bracket package stick through the motherboard and are secured with nuts. A set of insulating washers protects the board’s surface. If you own an AMD processor, you'll need to remove your board's cooler retention mechanism to accomplish this task.

The Janus provides 1.2” of clearance for DIMMs and motherboard devices, and is offset by 0.6” towards the side shown so that it can be rotated to clear taller objects. The bottom 80 mm fan needs additional space above the socket, but can be removed if necessary.

At 2.5” tall including its top 120 mm fan, the Janus is exactly the design we expected to represent the low-profile performance market. The fan even lights up for users of windowed cases such as ASRock’s M8.

If you need a second set of DIMMs to use with the Janus, you'll either want lower-profile memory or to rotate the cooler away from the memory slots.

    I knew the noctua was going to win before I even looked at the results.

    It is really nice to see a low profile round up when a year ago it was hard to find low profile coolers at all. I have to ask though, were these tested on an open bench or in an enclosure? I think to really judge them you have to put them in a box. Maybe not that silly ASRock chassis, but something a like a BitFenix.

    Also, every mini-ITX motherboard is a little different. It would take some work, but it would be nice to see coolers cross referenced with different motherboards for compatibility. Just reading reviews it is pretty common to find one or two "Didn't fit my board" comments while other reviewers found the coolers to fit perfectly.

    Several others asked us for a few additional millimeters of headroom, though that would have resulted in a viscous cycle

    Do you mean vicious? Because I'm fairly sure the cycle wouldn't be a thick liquid.

    I am surprised that the Cooler Master GeminII didn't make this list.

    i feel that only a few of them ( like 3 or 4 ) are really low profile coolers, rest are just normal size, bearing in mind that the big ones are labeled as tower coolers...

    Those things are WAY TOO BIG for really compact mITX systems....

    I'm using one from Titan that is really small: 107x70x12.5mm (official dimensions are incorrect) for the skived copper heatsink and can use 60mm or 70mm fans...i'm using a Titan fan that is 70x70x10.

    Really compact....check my build at www overclock net:D

    I i will add soon more pics and you will see something that is really small.

    I was going to post precisely that.

    I have one for my A8 8350 (100W) and it does a wonderful job inside a TT SD200.

    And this is the CM cooler we're talking about: CM GeminII M4
    Cheers!
