Currently I have a SLK800u. I find it to be decent, but am wanting to get a new SLK947u (since it's $19 at svc right now) and get a 92mm panaflo along with it (getting sick of this SF2). Can I mount the SLK947u with the SLK800u backing plate? Not really wanting to pull my mobo out and change out backing plates or shell out the extra $5 if I can get away with this. So.... SLK800u Backing Plate + SLK947u Heatsink = Yay or nay?
