i have the akasa k25... will only having 2 holes suffice?

 

 

 

im thinking about asking my plastic fabricator friend to whip up a couple plastic washers (with screw holes) to make the 75x75 work. thoughts?

The Akasa K25 works perfectly fine using only two diagonal mount points, after removing mine to install the noctua cooler (it was on for a few weeks at least) I could see the TIM had spread evenly allover, also the temps were fine.

Hello, 

 

Just I want to share with my first post, the mod I did to the Noctua NH-L9i. 

 

I just cut and reduced the brackets 10mm in order to fit the mobo holes. In addition I did have to make additional new holes in the brackets.

Now the it fits perfectly and firmly. I did add some cold soldering glue to the cut sides, was not needed though.

 

Now I have mounted it and supplied with the molex 12v and using the PWM from the mobo connector. But the fan behaves just the oposite as the case fan. Means if the case fan speeds up the cpu fan slows down, and if the case fan speeds up the cpu fan slows down. Any suggestions?

I had to cut the fan due to this motherboard connector but as you can see it now fits perfectly without a need of any extra fixation points.

I just wanted to say thanks for this.  I fitted the Zalman with a core i3 3240 and it worked a treat.

 

As I was going to be swapping out the motherboard and fan on my unit, while it's apart I thought I'd take the opportunity to look at other cooling options for the CPU.

 

This might be of interest to those who've fitted a 69W Xeon. You can see psikey's stress test of a 45W Xeon and the OE passive heatsink here, it stays quite cool.

 

There are two challenges fitting a CPU cooler to the Gen8; the minimal height available and non-standard cooler mounting holes.

 

Unfortunately rather than the standard 75x75mm mounting holes for a LGA1155, this motherboard has 75x65mm. That means the diagonal distance between the screws changes from 106.07mm to 99.25mm.

 

The solution I found was the Akasa K25. Due to the 10mm change in mounting dimensions, only one diagonal pair of mounts was going to line up.
