Does the Prolimatech Megahalems not do well with high-speed fans (ie. Scythe Ultra Kaze 3000)? I could imagine the cooling potential with this heatsink and two of those fans!

If 3000rpm isn't good for it though, what fan speed is? I currently have two Scythe S-Flex fans going at 1200rpms each.

Also, can the PM really outdo a TRUE120 (standard aluminum version)?

There's a review a page back that looks at that
It certainly beats the TRUE with a Nexus real silent @ 7v...

seems like the company were a bunch of former thermalright engineers who took their wares and started their own

apparently they were unhappy about thermalright's restrictions on their design and specs. so there we go.

thats pretty interesting, goes to show how Bureaucracy hinders innovative design.

after reading this review i purchased one of the Prolimatech Megahalems coolers and i have to say it's very very good. my previous cpu was a e8500 oc to 4.2 and had a tt douorb wich was just fine until i upgraded to a Q9650 and found the douorb struggling at an oc of 4GHZ with the Q9650 but this PM cooler is ever thing they say. I put a Nexus 120mm real silent fan on it in push (and the fan rarely go's above 1000rpm ) it idles around 36 and under 100% load never go's to above 60 so i am very happy with it temp taken in realtemp 3

I think on the expreview website they have showcased a DFI branded megahalem on their boards. I think this design with the split in the middle will be the design to come in future. It seems to be the best mix allowing best cooling in both high and low push or push/pull configs.

I read most of my reviews from silentpcreview. their reviews seems to be one of the most trustworthy imo.

I just read that expreview review and i didn't know DFI had made the PM there cooler of choice witch is very interesting and good. I suppose that tells every one just how good the cooler is.another thing is before i purchased the cooler i sent an email to Prolimateck and asked them if there cooler would fit on my P5Q Deluxe and within an hour they responded with yes that's bloody good service i recon.

I don't now how much better air cooling can go but it is seems to be a good design and it looks amazing installed and some reviews stated that you loose one of your ram slots i found there is hoops of room left on my board anyway

the ram slots being lost is only when some people purchase ram coolers that might stick up above the ram and impede installation of a large high powered fan for eg. 120x38mm fans that can push really high cfms.

I just recieved my new Prolima Tech Megahalem and i'm impressed by how smooth and straight the block is compared to the TRUE. Just gotta decide whether to lap my Q9650 before installing it.

only if u lap both the heatsink and the cpu will u get a ~4degree drop max... (based on what i've read in reviews of other experiments)
think of warranty issues. more than a year - lap. less than that - save it

Well i lapped it anyway and i did notice a 4-5c difference. I didn't lap the heatsink though. It's a great heatsink exactly the same results as my old TRUE with 2 x noctua P12's. I think I'm gonna look into watercooling though as its getting a bit noisy with the amount of fans i have in my P182.

Anybody know if 40-45C idle is okay for a NH-U12P running my i7 920 @ 4ghz?

This room can get quite warm as it's heated (ambient ~25C).

Load temps are fine, doesn't go much higher than 74C in LinX.

I might possibly drop it a little - those temps are a little on the "erk" side of things.

I've looked through the 6 pages and can't find a BigTyp 120 VX, currently using a zalman cnp 9500 have got a BigTyp 120 BX the cpu is a Q9550 will i see much of a difference in temps or can i up the vcore and still keep it at a good temp?

I think I've decided on the Megahalems to chill my chip.

A question about fans...

Low dBA is good I know. This comes generally from low(er) rpm. What is more important for a CPU heatsink fan though - volume of air moved, or static pressure?

Also, how accurate are the dBA ratings on fans, I'm looking @ buying from PCCG and it seems odd that some more expensive fans (ie, Scythe s flex and slip stream 1900 rpm) are advertised as 37 and 35dBA but the cooler master 2000 rpm is advertised as 19 dBA, quieter than the famous noctura NF-P12 1300 rpm fan...
Is this 19dBA @ 1/2 speed? Should I double the 19 to 38 for a more realistic estimate? Or iseveryone who's NOT using the $20 CM fans wasting $$$?
