Help - I no longer hear my PC!

First unpack the part and tried him on the mainboard (MSI Neo2-F V2.0 K8T) to assemble - crap! Since a capacitor near the processor socket is so stupid in the way that it is definitely not possible to mount the radiator. But for Arctic Cooling can nix.
So what now?
Shall I turn it 180 degrees and try to build the fan on the other side (so that it blows again towards the housing rear wall)? No, that would be nothing, because then the voltage transformers are not also cooled on the motherboard, for the freezer but has a few extra-so beautiful curved downward slats.
So we take it out the clip under the microscope, and lo and behold: The can be fully disassemble and make rotated by 180 ° turn again.
Prima! So now it fits properly on the mainboard's and blowing again in the right direction.
From this "reconstruction" (and the necessary during installation effort) apart once the installation was then unproblematic.
So, connect and listen ...
Well, after the fan is not temperature controlled, and my motherboard does not have a fan control, he was with his 2200 r / min already a pretty annoying rowdy.
So nothing like a resistor cable dazwischengehängt that regulates it to about 1,200 trips down - and you can hear nothing more, and the CPU temperature stays loose even under full load in the green zone. Perfect! Now is my PC right next to me, and I no longer hear him. Direct used to ...
So if you either have a motherboard with fan control and enough space around the processor socket around or a little craft skill and the necessary accessories features: 5 out of 5 stars, otherwise you should consider if you do not want to look for nem other cooler itself.

Update (14/12/2008): The tinkering is no end: For mounting on my new socket AM2 motherboard (MSI K9N Neo-F V2) I now had to nip off even the corners of the retaining clips with a Saitenschneider so the cooler on retention module fits - which has not namely three retaining lugs for Kühlerbefstigung, but only one - and where should be the two outer, already the retention module comes around the corner.
But even that is actually another shortcoming that MSI has not screwed up and Arctic Cooling (Arctic Cooling has on its website even on the MSI AM2 boards down!) - So I stand by my review, because the radiator is still top ! The Athlon X2 4850e cools now anyway confidently turned down to approximately 900 revolutions.

Update 2 (13/12/2009): Meanwhile potters in my computer a Athlon II X2 250 with new cooler, the Scythe Katana 3 and after its installation I have the Freezer unfortunately subsequently still deduct a point, namely Scythe shows how a truly easy installation works. Since Arctic Cooling may well learn something ... I, however, the performance of the Freezers - especially given its price - still find amazing, he has earned his four points still honest.
