Cooler Master's Hyper 6+
The last heatsink we'll be looking at in this review is Cooler Maser's gargantuan Hyper 6+:
Weighing almost a kilogram and measuring 118 x 82 x 143mm this is a serious contender for this year's 'ridiculously large heatsink' award.
In design it's very similar to Gigabyte's G-Power; heat-pipes link the copper base to aluminium fins which are cooled by a 10cm fan. The layout has changed though, the fan is side mounted to blow in the direction of your case's exhaust fans, aiming to get the emerging warm air out of your case as quickly as possible.
As with the Vortex the fan is supplied with a four pin connector, if your motherboard supports the feature it will allow you to reduce the fan speed to 1800RPM which will diminish the noise it produces to just 20dBA. If your motherboard doesn't have four pin fan headers you'll be limited to running the fan at full speed (3600RPM) and a reasonably noisy 46.4dBA unless you add a fan controller of your own.
Installation of the Hyper 6+ is exactly the same as for the Vortex, it allows you to mount the heatsink with the fan pointing along the length of your CPU's socket or perpendicular to it; you needn't fear that the cooling fan will be pointing in the direction of your case's exhaust.
We were left feeling quite lucky that the Hyper 6+ didn't conflict with any components on our test motherboard, and as the second picture above shows, the heatsink almost stopped us refitting our test case's side panel after installation (Praetorian 731).
