Would this work?

I have the Thermalright Ultra 120 TRUE and the way its mounted is unfavorable for air flow. Granted its not terrible I have 4 fans for intake, 3 coming from the front and 1 from the side with 3 exhaust, 2 in the back and 1 large one on top. As of right now this is sort of how my airflow works I'm assuming.

Red represents hot air/exaust
Green represents cool air from side fan
Blue represents cool air/intake

Doesn't look like it flows too well to me..so what I would absolutely love would be to rotate my HSF 90 degrees and I've been searching and searching and searching for something that could do that and I finally came across something that might work and I know its not designed for work for this heatsink, but the specs of both are very similar.

Prolimatech AMD retention mount adapter kit which is designed for this Heatsink, Prolimatech Megahalems CPU Cooler. If you compare the specs of both heatsinks they have relatively the same dimensions and they both weigh the same, but it just doesn't seem like it could be that simple, could it? I'm hoping for some input from you guys, because this seems too good to be true.

Oh and I made another diagram of the projected air flow if the heatsink was turned.

Looks a lot better if you ask me.

Prolimatech - Megahalems CPU Cooler /// Thermalright Ultra 120 TRUE

Dimensions: (L)130mm X (W)74mm X (H)158.7mm /// (L)132mm X (W)63.44mm X (H)160.5mm
Weight: 790g /// 790g

I think it might be better if you make the two rear fans intake also and just let the top fan which is what 180mm or 250mm pull the hot air out. Hot air rises to the top so pulling hot air from the top to the rear is just getting in the way of the rest of your Airflow. At least that's how I look at it lets see what other people have to say. As for your HSF that adapter might work but I kind of doubt it.

Thanks for the quick response :)

Thats not a bad idea really..the thought never occurred to me to change the direction of the two exhaust fans, I'll try it out.

Oh, and the only problem I saw was the Megahalem has a thinner copper base which is pretty much the only thing holding me back from trying this.

If it connects to the heatsink the same way then it should work I would be worried that it wont touch the CPU all the way.

Well considering the Thermalright has the larger base, in theory my problem would be the screws not being long enough to reach the threads of the backplate.

Are they regular screws if so then you can easily get some longer ones at lows or home depot. You could always order it and try it and if it doesn't work then you can RMA it and get a refund jab-tech has better customer service then newegg from what I've heard.

No they're push-pin screws. Heres a picture of it.

However I think I have some longer screws from my thermalright heatsink, they were meant for the intel setup, but they might work. Dunno, I ordered it so I'll let you know :D

OK cool let me know how that works for you.

They are spring tensioned bolts/screws, and it should work with the true ok, and actually you may get more pressure since the TRUE has a slightly thicker base than the prolimatech does.
 
Got a lapping kit too, seems like my thermalright has a bulge in the middle of it, hopefully after this new mount adapter and the lapping I'll finally be able to shoot for the 3.9 and 4.0 mark.
 
My friend has his setup liek this and seems to get awesome cooling of about 35c idle over clocked to 3.6ghz on intel q9450

So, heres the results. The kit was a miserable failure. I hadn't quite looked it all over and thought it through real well otherwise I would've noticed this before buying.

Take a look at the Megahalem

Notice those two holes located on the base? Those holes are used with the mounting kit. Take a look.

See the indentations on the bar. So, this resulted in quite a problem trying to use this kit on my TRUE, I had to saw off a few things like the two extensions on the mounting kit to make it fit correctly. Then there was the problem of the base of the TRUE being just too thick for the screws to reach, so I used a different set of screws that were meant to be used for the TRUE's lga1366 mounting setup. Which worked, but then I had the problem of there not being enough support/control of the heatsink, without something for the mount to hook into on the heatsink it moved around a lot, so I didn't even bother trying to stand up my case with a setup like that. Maybe if I had some metal fabrication experience I could get it to work, but for now; I don't see this going anywhere :(


On the plus side, the lapping kit reduced my idle temp by 3C and my max by 6C. :)
 
Why dont you use the AMD mounting brackets from Thermalright so that the air is flowing across the chip and out the back as pictured from BigRich. Unless you have space issues generally mounting it in this way will give the best temps.

Who is that and where are the pictures?

Edit: And the link to the place you saw that.

Thats intel not AMD, theres a big difference.

Intels bracket is a square so it allows for 90 degree rotation. AMDs bracket is a rectangle, so I don't have that option. Thats why I've been looking for a special mounting setup to allow for a 90 degree rotation, because your right there would be a much better air flow and cooling since it wouldn't be pulling hot air from my GPU, which is another thing I'm looking into doing. Moving my graphics card down so its not so its not so close. Just need to get some 90 degree sata cables.
