Down-Facing Cooler

post #1 of 9
Thread Starter 
I have noticed that many people own coolers like the TRUE and Tuniq Tower (uprights) as well as the Noctua NH U12P. But, how well do down-draft coolers such as the Thermalright SI 128 SE and Noctua NH C12P compare? They are cheaper, and they fit on more motherboards.

I was going to come in here recommending that C12P before even reading what you had posted.

It would be my choice as my next cooler, downward facing coolers are great, they add airflow to the mosfet area

I can't find them anywhere online, though. (I am in the U.S.).

Geminii cooler is a major downdrafter, $36 and you get to pick own fans. Installed 3 in builds myself, very large.

I personally strongly favor down-blowing heatsinks. Though they can sometimes be inferior to a HSF that has its fans blowing parallel to the motherboard plane, the difference is not a big enough advantage in my opinion.

The huge design flaw of a parallel-blowing tower-style heatsink is that the CPU socket area receives no airflow. Consequently, you get a huge pocket of heat collecting just out of the air stream from the heatsink's fan; there is an aerodynamic dead spot where air does not move, and cooling suffers. Unfortunately, MOSFETs/PWMICs/voltage regulators are almost always located in these areas immediately surrounding the CPU socket. Tower-style coolers might cool the CPU by maybe 2-5 degrees C better than a down-blowing equivalent, but everything else suffers from the lack of air movement.

You must counteract this very real weakness of the tower-style cooler's design (by aiming spot coolers at the dead spots beneath the cooler) to prevent the very real possibility of damaging your motherboard, in my opinion.

I am a strong supporter of down draft CPU coolers. My over all temps have never been better. Very pleased that I chose this route for CPU cooling this time around.

Check out txtmstrjoe's article I have linked in my sig. A MUST READ!

The C12P is really new, and as far as I know only pre-release right now, or is just currently OUT OF STOCK everywhere. Keep yourself updated at these sites..


For fun sake, here they are in CANADA at $65

And NCIXUS has them for $120

I don't really think the downward facing coolers really impact temps that much. The review I have seen that actually measures MOSFET and chipset temps with a Gemini have shown that there is zero to negligible difference with a downward facing cooler.

Run a CPU cooler of any sort and put your hand on the other side of the heatsink and see how much airflow is coming out.

If you have a small case then I whole heartedly recommend one of SI 128 SE or NH C12P's.

Sorry but my temps on my 680i def. made a change for the better! Of course the CM690 is great for my set up!
