Up Close

We have to say we do like the sleek satin black boxes used by bequiet.  Inside along with the cooler there are the usual fittings along with a  single set of spring clips (the fan does not come already attached to the cooler so these are not spare spring clips)  The cooler already had TIM coating the base so bequiet haven't included any TIM syringe.  This of course is fine, but it does mean if you need to re mount you're going to need more TIM. (Please note we removed the TIM and tested with the same Noctua TIM as used in all the tests)

The cooler itself is a 120mm fan based unit measuring as it does 155mm in height, so it should fit into most mid towers.  At just 87.5mm deep with the fan fitted it shouldn't give you any RAM issues either.  Heat is drawn up from the contact plate via four 6mm copper heat pipes, all of which run very laterally within the 48 element fin stack

The top of the cooler is finished in a satin sheened Aluminium panel, with the bequiet logo picked out in black.  The copper heat pipe ends are elegantly capped so as to keep the whole lot looking classy.  The contact plate is copper but is Nickel finished, unlike the heatpipes which exit it.  There is some evidence of solder splatter around the junction area.

The Pure rock is a bit of a faff to fit, with the process not made any easier by next to useless instructions.  The diagrams aren't great, and the sentence structure and use of English leaves you feeling even more confused.  Once in though the Pure rock looks quite nice, and not too lost inside the MasterCase Pro5.  For a 120mm fan based cooler the Pure Rock performed quite well, and certainly a lot better than some of the other larger bequiet coolers.  This we think is down to the Pure Rock having a better attachment method and so greater contact with the top of the CPU.

Had a quick look..
dont see any AIO's in there as a comparison.. I think it would have been nice to see atleast 1-2 of the most popular ones in there, it would just round out the comparisons a bit better imo if you also factor noise efficiency and redundancy.Quote

Great article, good to see my D15 is still a beast in the air cooled department.

One small thing, while reading the D15 page I couldn't help but notice something wrong.

Quote:
With the front fan installed you are though limited to standard height RAM.
This is actually not the case, the fan can be positioned forward due to the design of the mounting which allows for big RAM if you have the case clearance for the fan to protrude off the cooler.Quote

That explains all the hype around the Cryorig lot, good prices and performance there. Great to see so many all together in one place for comparison.Quote

The BeQuiet coolers are meant to be tightened from the back of the motherboard, not above and between the fins. No wonder you found it hard to do.. If you are saying that poor fitting is the reason they don't perform well, then the test results are not representative of the coolers performance.Quote

I bought the Be Quiet Dark Rock TF for the looks for the Lian Li Q10 build - was supriced that it placed so low.

Have the Raijintek Pallas on my living room rig cooling a G3258 and I thought it was great.Quote
