was waiting for my cm black widow to come through and finally got the ninja installed today, mucho hassle!
got the bracket installed on the motherboard, looked on the floor and one of the washers had falled out, argh ffs, took it apart and put the bracket + washers on properly. didnt really want to stick the underside mounting plate to the mobo.
then i couldnt get the wires which hold the fan up to go on a certain way even though there are notches on all 4 sides (the tabs that hold it to the mounting bracket got in the way), thought sod it, cba to take it apart again i'll just have it blowing up even though its right next to my 8800gts which blocks most airflow.
go to slide the tray in, nooo wouldnt fit! ended up taking the whole thing apart again to reorientate the brackets so i could mount the thing facing up but first sliding the tray in.
its a tight fit in a coolermaster black widow case, it only "just" fits! shame i would have to take the ninja off to use my removeable tray, im not a fan of removing hsf's once they're installed so im not planning on taking this rig apart unless i have to.
a quick test shows that temps are much better now, with the intel hsf, at 2.7ghz, running orthos for 5 mins made the temps rocket upto 70C and i'd always bail at that point! a quick 10 minute check and temps were around 55C. though thats with a 120mm scythe fan running at what i assume will be 12v, it seems to be running at around 800rpm but waiting for one of those 5v 3pin adapters to come through the post to quieten it down some, that or i can 5v my case fans..
