I just got a xp-90 with a 92mm panaflo ultra hi speed 69cfm fan. I have the fan attached to a fan controller, to keep it quiet. I was using the stock
hsf and temps were 43c now they are 36c. Working my way up to 2.7 now, btw I have 1gig of bh-5 ram and had to do the vdimm volt mod, as most of you all know the bh-5 chips love volts, I've had these chips for about 2 years now and have been pumping 3.2 volts to them for that long. That's what was holding me back earlier.
