Question  Question by Gumball


Would this be compatible with an ASUS Sabretooth z77 mb (worried about the motherboard casing),i5 3570K and corsair vengeance memory (either normal or low profile)

If not could you recommend a decent fan as I am looking to overclock.

Many thanks

Hello Sir,

Yes this is compatible.

Thanks for your question

 Very quiet and cool, would recommend by Chris

I was going to buy the "Zalman CNPS12X Ultimate Performance Triple Fan" but I found myself drawn to this the "be quiet! Dark Rock Pro Dual Fan".

The cooler arrived Friday and was instantly taken out of the box. It's definitely a big and heavy fan weighing in at approx 1KG.

I fitted this cooler to an Asus P8Z77-V Deluxe without any problems. The heatsink and fan extends across the DIMMs so full height performance memory with the heatsinks won't fit. I'm using the Corsair peformance memory but the low profile version, that fits with just over 1CM between the top of the memory and the fan/heatsink.

It stands 17.5CM off the motherboard so ensure your case is deep enough. Most gaming cases should be ok. The CM Storm Trooper which I purchase has 3CM from the top of the heatsink to the side panel so plenty of space.

When I first connected the cooler and powered on the computer I hadn't made any changes to the Bios so I received an error. "CPU fan error", after checking it would appear that by default Asus configure the motherboards to alert if the CPU fan drops below 600RPM which this does. Less effort is required by the cooler so as standard it runs at 500RPM until put under some above normal load. Dropping the alerting threshold to 400RPM fixed this issue. Just something to be aware of.

Performance Testing:

I have an Asus P8Z77-V Deluxe with a i7-3770K clocked to a conservative 4.2GHz. During standard usage like browsing the internet and editing word documents it runs at approx 30 degrees with the fan steady at 550RPM. After running Prime to stress test for two hours the CPU reached 55 degrees with the cooler never going about 1000RPM or 70% of its maximum duty. This was with the case fans lowered to the minimum setting.

At 900-1000RPM the cooler is still quiet.

Overall I'm very impressed.

Question  motherboard space by colin

im thinking of getting a ASUS Maximus IV Gene-Z.will this cover the first mem slot,or will i have too get lp corsair vengance

Answer by joebe on Tuesday, May 1, 2012
Yes it will creep out onto the mem slot so i would go with low profile memory to be certain.

helpp by marty

will this fit your arianet dominator midi case? i have 2x4gb of ram but theyre in the 2nd and 4th ram slots so theres one slot this could hang over if necisary? cheers

Response by joebe
I believe this fan MIGHT just fit but it will take up a large chunk of space and wont be very good for cooling/circulation. i would go for a bigger case or a smaller cpu fan such as (47249)

Question  Will this fit by Mac

Will this fit with mushkin enhanced blackline RAM

Answer by thomasr on Sunday, April 15, 2012

Yes it will.
