What fans do you suggest? I'm going to be doing as much overclocking as possible (on air). I'm not worried about noise from the fans, just max cooling.

Also, is the black deluxe edition identical except for the color? Does the black coating help/hurt it's cooling ability?

Any other thoughts?

The black coating on the Mega shadow will hurt the performance a little, its up to you if you are okay with the cool looks though. It shouldn't do more than 1-2 degrees though.

For fans, i think this would be your best option...

Superior cooling ability and a decently low noise level. Keep in mind 37dba is NOT silent.

get a 150CFM delta, other than the 747 noise (at full throttle) you will be fine =)

LOL! I really dont mind the load noise, so i have some of the cheapest loudest fans out there.

The fans that i linked had better aisr flow, but were a little louder.

Once you start thinking about maximum airflow for the cpu you also have to start thinking about maximum airflow into and out of the case. That means replacing all stock case fans with new fans that can keep up with the heatsink fans.

Back in the good old days when noise was not an issue we used the Panasonic Panaflo heavy duty fans. They could move massive quantities of air. They are still readily available:

Prolimatech recommends 800 - 1200 rpm....unless you want it to sound like an airport, I'd follow that recommendation. I'm sitting next to a Megashadow w/ twin Enermax Magmas rated at 1500 RPM 69.15 CFM and 18 dBA. Remember that the sound test rating of 18dba is on a test bench and measures fan noise when not smacked up against a bunch of tightly spaced fins creating air turbulence. I have the fans turned down to 83% speed at which point they are basically inaudible....at 1500 rpm, they are annoying (in other words audible) and that's an 18dBa fan

On the other hand

The Kaze's 3000 RPM and 45.90 dBA is more than 9 times louder than the magmas
The Slipstream's 1900 RPM,37.00 dBA is almost 7 times louder than the magmas

If ya want a Scyth fan, I'd recommend the 1300 rpm, 26 dBa PWM model .... here's a shopping list.

Though there is a Megashadow sitting in the box next to me, if I had to do it over , I'd get a Megahalems Rev B. When we purchased, Megahalems only had 1 fan clip (Rev B has 2) and though both Prolimatech and the reviews I read showed no performance difference, the black coating only looks cool sitting on your build bench. Can't see it when strapped w/ fans and in a relatively dark area of the case even w/ UV lighting and case window. Using PWM will allow MoBo to control fan speeds. Most enthusiast MoBo's have fan header ratings of 2 amps. I'd limit combined fan pull to < 1 amp on that header tho.

Jack - You still there?

Do you have a reference for that Prolimatech recommendation? Just curious to see what else they have to say about it. I remember you mentioned it before. I went to the Prolimatech web site but could not find it. Actually it wasn't much of a web site considering they offer some very successful products.

Jack,

I'm a little confused. Are there only 2 (up to date) Prolimatech coolers (Megashadow and Rev.B)? I thought the Megashadow was available in the standard color and also the Black edition. Was I mistaken? If there are 3 editions, which performs better between the Megashadow (non-black) and the Rev.B?

I'm not concerned about the looks of it - just cooling.

I plan on using the HAF 932, so does that change your thoughts on the (likely) desirable noise levels? The 932 has a bunch of monster fans and mesh sides, with the biggest fan being on top.

Thanks

Here is a link to the Prolimatech web site showing the three cpu heatsinks they offer:

http://www.prolimatech.com/products/cpu_cooler.html

I have my emergency back-up system in a Coolermaster HAF 932 case with stock case fans. Ventilation, airlfow, and cooling are excellent. Those extra large fans run at lower rpm so they are not as loud as one would think.

Jack - never mind. I found the fan rpm recommendations in the product descriptions at the Prolimatech web site.

yea same here, im not into low noise PC's... The louder the better, of course a fan controller is a must in these situations....

^haha, yeah. Or just wire them up to a potentometer yourself. :lol:

Just an e-mail....might have saved it on my other box. Can tell you from experience tho....the Magma fans at 1500 rpm are LOUD. At 1200 rpm virtually inaudible.

Many will not want to disable the boot warning and stop that comes from not having a fan connected to the CPU. As a Dad, I certainly wasn't going to figure a workaround on a teenager's box. :)

I chose to go "low noise" and used 2 Noctua P12s. Now its the only configuration I've tried, so its hard to compare. They are running full power, which is spec'd to be 1300 rpm. So quiet, you wouldn't know they're on. Temps don't appear to be quite as impressive as reports I've seen from others, but one never knows if comparisons are apples to apples.

I see 72, 68, 68, 72 after 2.5 hours of LinX, with 171x21, vcore(bios) of 1.3125, LLC DISabled, vdim of 1.6v, vtt of 1.21v. Temps are reported by coretemp. That's another variable, of course.

Cheers,
Bob
