Thermalrigth AXP-100 showed up today!

I don't think it makes any difference. Heatpipes work in all orientations. Back in 2008 Noctua took issue with Legit cooling review of NH-C12P. Noctua claimed the orientation Legit resulted in lower scores. They retested and got .25-.75c difference by orientation. Well within tolerance (<+/- 0.5c)

Thanks for that :)
I agree with you, just wanted to check how they packaged it.
 
Found a review showing lower temperature using TY-100 pulling out of AXP-100 than pushing in so I did some runs to see. Ends up it's the air blowing down into cooler that is much cooler. Air blowing down through AXP-100 hitts motherboard and goes out hitting the GPU, RAM, I/O housings, etc and comes back up around cooler and is sucked back in by fan. With fan pulling air out of AXP-100 goes up and away. Hopefully your case has a vent and/or fan that catches it and removes it from case. CPU is 5-7c cooler with fan pulling out of cooler.

:doh: I re-ran a couple of the fan pushing in tests. Intake air is much warmer than room ambient.

. 2450rpm is maximum rpm mounted pulling out

Running TY-100 pushing in again and finding the heat difference is because of air temperature over cooler / fan intake. Idling at 2400rpm the air 30mm above AXP-100 is 28.5c with 22c ambient. That's with a TY-140 40cm away and 15cm above work top blowing 22c ambient over test setup.

From now own I'm going to worry more about what actual cooler intake temperature is than ambient temperature. :rolleyes:

Well, 11 months later and don't have a single complaint. I recommend the AXP-100 to anyone needing a good low profile cooler.
