What a pain...
I installed the Titan Fenrir cooler yesterday. Firstly i've got to say how well packaged this thing was. It was hidden between two 2 inch thick blocks of foam inside a protective box.
The installation was a nightmare if i'm being honest. I took my the best part of three hours to do.
I stared with taking the stock cooler off of my CPU and cleaning them both with the ArctiClean TIM Remover And Surface Purifier which left my bedroom smelling of a Terrys chocolate orange for hours!
I then attached the bracket to the cooler, and fitted the four washers. I then took all of the screws off of the original back plate to get that off, only to find that the cut out on my case was about 2mm too small to i had to take out the graphics card, internet card, fan controller etc. and unplug my psu from everything and take my whole motherboard out of the case.
I then asked my brother to hold the cooler while i flip my motherboard upside down and then put it underneath. He took it from me, tipped it the wrong way round and dropped two of the washers. It then took me an hour on my hands and knees to find them both as they are made from a clear plastic.
Once found, i fixed the cooler to the motherboard using the smallest screws i have ever seen.
I then put the motherboard back in the case and screwed it back to it which was also a nightmare as the cooler is so big!
But after all of this, it is now in my case with the two fans in push-pull. under load, it is about half as load as the stock cooler at idle. My idle temps went from mid 40's to very low 30's and my load temps went from high low 70's to low 40's!
So all in all, this is a great cooler, it's just HUGE and used very tiny fiddly screws.
Im also going to try over clocking it further later today and see how it handles that.
