thanks man! just what i was looking for.
it seems the 9900 performs a bit worse than the old 9700. so looks like i'll be getting the 9700 from the results of that review.
I think the CNSPS9900 performs better but bear in mind it does have a correct orientation. If installed upsidedown it is worse than the older 9700. The 9900 has a bigger side with two heat pipes and slimmer side with one heat pipe. The bigger side is supposed to be positioned upwards or towards the exhaust.
