Hey, yeah I read about the "TMPIN2" (the 124C scared me!) and in other places for this board they chalked it up to a sensor issue not reporting correctly to this tool. So I doubt that is the issue as it never seems to get too hot?
Yes, I can confirm that the fans are there and working.
I built this system a few years back so it's a little tough to remember the full specs in detail but here goes:
-AMD Phenom 9550 (Quad) now (When originally built this was a Dual core, but was swapped to an X4 a year or so later)
-Originally used a 9700GT I think, then installed the Palit Radeon4870 Sonic at the same time as the X4 CPU, now its a Zotac GTX460 (756mb)
-Arctic Cooling Freezer 64 CPU Heatsink
-4 gigs (Dual Channel 2x2g) Buffalo Firestix RAM (1066 5-5-5)
-Azuntech HDA Xplosion 7.1
-Asus M2N-SLI Deluxe (nForce 570 SLI)
-OCZ 520ADJ-SLI Powersupply
-1x Seagate Barracuda HDD
-Samsung DVD Burner
-Floppy drive / card reader combo
-Thermal Take - Matrix case (front is mesh with a filter so it's one big air intake)
-1 fresh air in fan blowing through front (80mm)
-1 120mm case exhaust fan right behing CPU cooler output
