What's wrong with the Be Quiet Dark Rock Pro?

post #1 of 8
Thread Starter 
It looks like a beefy cooler, certainly comparable in size and weight to a D14 or Silver Arrow. And it comes with two 120mm fans that spin at up to 1500 RPM, so the airflow is comparable to a D14 or Silver Arrow as well.



Size comparison to the Silver Arrow:



So, why is the performance so much worse than the D14 or Silver Arrow's? Several sources have tested it, and the performance is lacking:




Even with 2 fans, it's worse than an Archon with a single fan:







Can someone explain why the performance is so much worse compared to the D14 or SA, despite the similar size, weight, and design?

No explanation. Some heatsinks are just better. That's why we read reviews.

One thing are the fans, wich are not the best for a heatsink/rad. They'll release a new revision soon with bigger 135mm fans (120mm mount), wich will increase the performance by a few degrees i guess. Also it doesnt perform THAT bad. i had it like 5 degrees behind the Silver Arrow at a 4 GHz overclock.
in this review it's about 3 degrees worse than the SA.



Again, the new version with more suitable fans might work a bit more efficient.


and i dont trust the oc3d cooler reviews, because the guy changes setups for his tests (case/casefans) and has some really akward results sometimes...

What about the XBbitlabs results? Dark Rock Pro is a full 6C worse than a TR Archon, even when the Archon only has a single low speed fan and the Dark Rock has two medium speed fans.

the archon is also better than the silver arrow @xbitlabs...

And the archon/silver arrow use 140mm fans, you cant compare the rpms ...

I hope you won't mind me asking this question here, I was just wondering, if it would be okay to remove its outer fan to make room for my dominator RAM? I know it won't cool AS MUCH but would it be within acceptable limits?

Best regards,
Jonas Frederik
