Acceptable Mobo Temps?

[effee]

When i open up my side panel, and blow my room fan at max speed onto my mobo, it drops down to 35C, its a Asus K8V SE DLX. but when I turn the fan off, it goes up to 46C, is this acceptable? If not, how do I bring it down. Also when I first bought this rig, the temps never went above 40 even without an exterior fan blowing at it. Now I have to use my room fan to lower it down to <40. I'm running an icute casing with 3 fans..is that enough?

How long has it been since you put the heatsink on the cpu? I have found that over time, the paste between CPU and Heatsink seems to breakdown or not transfer the heat to the heatsink. About once a year I clean off the old paste and add new paste and reset the heatsink. A few weeks ago I was complaining about high CPU and MB temps. Adding the new paste ( Artic Silver 3) has brought the Temps back down by about 8*C. Also I'm using 2 intake fans; 2 exhaust fans; in each of my 2 PC cases and the Power Supplies are of the dual fan type. I figured I had more than enough air flow, but still saw high temps.

This rig is about 2 months old. What are you temps like?

CPU's before replacing the paste were 56* to 58*C and MB's were 30 to 32*C. After new paste: 47* to 50*C on the CPU's and 27*C on the MB's. Room Temp is 20*C. I have been leaving the PC's on all the time; as I'm running the SETI@Home Work Units.

Are you using the AMD supplied Heatsink &amp; fan ? If you are and it's the aluminum base; you might try another fan Heatsink Combo with a copper base. I use Vantec Aeroflow's on my XP2800+'s; but Thermaltake and CoolerMaster make good units as well. Just be sure to find the right size for your CPU.
