Xp90 here with an ACRyan UV 92mm fan 2500rpm and about 45CFM
ambient: 24ºC
idle at 950-1050rpm: 36ºC
load at 2650rpm: 46ºC
I'm considering lapping the XP90 base (so i'm considering to purchase a good lapping kit XDDDD ), but I'm scared to remove the "nickel plated" and get things worse.... but now seems that heatpipes don't get as warm as they should be... maybe a concave base?????
