The assembly is fiddly detail. That means:
First of all one must unscrew the previous holder on the board. You have to work very slowly, and with the other hand hold the plate on the back. Power to do so may veer these left and right and scratch the board from behind.
If you have done this, you have to put a bigger plate from Mugen to the back and tighten with extra screws on the front. If you have done this, you have to mount the retaining clips on the screws.
Now Substituting cooling paste on the CPU and the Mugen cooling block it. Then you define a sort of holding rod under Mugen through and screwed it firmly with the retaining clips. Depending on practice in something that lasts 15 - 30 minutes.
Last but not least you befässtigt the brackets with the fans on the cooling block and connects the fan to the PWM connector. This may take up to 20 minutes.
Unfortunately, this cooler also negative:
Compared to Mugen II, version 4 has been quite strong in the breadth and offers instead of on all 4 sides, only on 2 sides an attachment. Are you saying that the provided cooler mind. Surmounted 2 slots from Ram. Assuming a fan with 12mm wide instead of 25mm, it is only one slot. Putting the fan on the Mirrored page, the CPU temperature increases by about 5 degrees. But one has however again all Ram slots.
So would rather a Scythe 12 mm fan, to settle instead of the 25mm fan. This needs to buy only one, unfortunately.
Conclusion:
The assembly is a very fiddly Feinstarbeit. A beginner I would advise against this right of assembly.
So I find the installation of a water cooling system simpler than that of this fan !!!
