Got my board and playing around with how I'm going to step up the cooling a little.

First off, I fabricated my own two heat pipe transpiper from an old HR-05:

I had a couple of old Thermalright HR-05 SLI's lying around from my 680i chipsets before I went to water with them, so I started pondering how I could convert one into my own home brew transpiper.

For starters the base for the HR-05 is too wide. At a minimum you would need to sand off or cut off the extra width and then drill and tap a hole in center of the HR-05 and drill/tap a 4-40 hole in the DFI PWM sink.

I did just that

and since I had the mill I went a step further and cut down a flush slot in the DFI sink so I'd get full contact on the base.

Turned out pretty good I think, now I'll have a little more cooling and no more tubing clutter from yet another waterblock. I also have an ultra low speed 80mm fan I mounted to the HR-05....I think this will work.

Here is the slot I milled out in the stock heat sink to provide full contact.


And here is a comparison with the stock HR-05 SLI base, I had to cut off about 2.5mm on each side.



You could do this mod yourself if you happen to already have one of these sinks lying around. You could just use a belt sander to take the sides down, then drill and tap the hole in the center, there's probably plenty of contact bridging over the heatpipe slot for the stock transpiper.

Cool little project, I'm already enjoying the board that much more now that I have something custom on there..

The stock transpiper just has a single heatpipe...this has two..


Picture of the stock PWM paste mess that was left behind...I think they use "Enough"..



After cleaning up:



Also qdemn7 from the liquid forum spent some time measuring hotter chips on the board, I thought this was great info to share for some potential chips you might consider putting some small heatsinks on:

After 2 hours of running Prime 95 v25.6 build 6, at stock settings, system below I get the following results:

The 3 chips outllined in red are the hottest. They are running around 47-51C.
The 3 chips outlined in yellow are next, they running at 43-45C.
The main heatsink for the mosfets above the CPU is running34-36C.
None of the rest of the chips on the board get above 40C.
Ambient temp is 26C.

This is sitting out in the open on a Top Deck Tech Station.
