Basically, Thermalright realizes the SLK900 doesn't fit all mobo's, so they did a redesign. A trimmed down SLK900 that will still fit 92MM fans, but should fit on any mobo that a SLK800 fits. Weighs about the same as a SLK800 at 527g. And it will have a 3-prong clip instead of bolting to the mobo.


From Thermalright:

" While in attempt to achieve high performance and low noise, SLK-900U had no comparable rivals in the current market. However its unique fin orientation and the complexity of installation had pushed many enthusiasts away. The design concept for the SLK-900A was to match the performance/noise ratio of SLK-900U, while make it more users friendly and better compatible for Socket A motherboards. With these perimeters in mind, our engineers went back to drawing board.

"The total fin area on SLK-900A is virtually unchanged from SLK-900U, this ensured great thermal dissipation from SLK heritage and superior thermal capacity, meanwhile the angular base has been redesign to better guide the blow down air current to every fin and reduce back pressure to extend the MTBF for the fans while decrease the center of mass, said Chief RD Engineer Scott , "by rotate the fin orientation we effectively avoid just about all the capacitors previously would get on the way, and our 6 prong heat sink clip will hold this mammoth on the CPU socket closely on the CPU die." By using 92mm fan, users can move same or more CFM of cool air thru the HSF to cool down their scorching CPU, while the fan rotates in much lower rpm to reduce noise.


The weight on SLK-900A Heatsink body is roughly the same as SLK-800 due to redesigned base plate. User can enjoy the ease of installation without worrying heatsink falling off CPU socket."



Comin' soon. :)

I wish they'd redesign the SLK900U to fit on the Asus A7N8X Deluxe without having to bend capacitors. I like using the motherboard mounting setup rather than the clips.

Try the SLK800U. ;)

It will fit 92mm fans, but may require some bending of one clip.



You're welcome mechBgon. :)


Should have one in later this week.

that'll be a nice solution to that 'extreme/severe capacitor bending required' for those a7n8x owners who want a 900U

thanks blade

From what they tell me, around August 11.

It's a nice puppy. Kind of a cross between a slk800 and slk900. Main benefit besides the 3-prong clip and that it'll fit most mobo's is that it fits the 92mm tornado.

Normally, I despise that fan because of the jumbo jet loudness. I connected it to a sunbeam fan controller and at 2600rpms, I can't hear it. 3k and under isn't bad at all. When and if you need the power, it is there. Though from my testing results, a cpu can only be cooled so far with air cooling.

Thanks to the fan controller, I'm hooked on using the 92mm tornado.


But if you have something like a SK-7, SLK800, there is no need to invest in the slk900a. Unless you must have the "king Kong" of combos. Only time I saw a difference between the slk800 and the slk900a is when using the 92mm tornado. It won't fit on the slk800.

Now Thermalright makes a "U" version of the SLK900a, see here. Looks made to fit AMD and Intel. Not positive on that part yet though.

the 900-U has been around much longer than the 900-A. and yes, it does fit both Intel and AMD, and the kit comes with mouting gear for both. I think the Intel mounting system is easier...

I know that, but this new one is called the SLK947U. ;) My mistake for leaving the name out. Just thought one would check the pic first.
