Heat problems with VNF3-250 and 3200+

[acivick]

DL'ed the 7/29 BIOS today for the VNF3-250. Went from broken temp readings to idleing around 60 deg C to 70 C load. I thought that was pretty high, especially since I'm running stock speed/voltages (2.2GHz, 1.5V).

Here's what I've done so far:
Checked to make sure nothing was blocking the fan (there wasn't)
Checked the fan speed (~3000RPM)
Opened the case while it was running (little to no change)
Replaced original thermal pad on the stock cooler with AS Ceramique (2-3 deg change)

Anybody have any ideas? Time to swap the stock cooling for something with a little more power?

Maybe I'm speaking beyond the extent of my wisdom, but 60-70C seems high. my 3500+ runs around 40C according to the motherboard monitor, although I know those values are not the true temp of the processor -- you need some sort of external thermometer to get an accurate reading apparently. I have a Thermaltake SilentBoost K8 HSF and I used the thermal grease that came with it. I have an old GeForce3 in my case right now, so that's prolly helping my temps.

Since runnig the proc with the case open didn't change anything, it might be a software glitch due to the new BIOS. Maybe you could get a hold of an external thermometer and try to reproduce the temps being reported by your mobo.

I was thinking it might be a glitch in the BIOS too, but there are others in the forums with the same MB, CPU and BIOS with more reasonable results (40-50 degrees).

I supposed it is possible that it might just be my particular MB or CPU, so I might just have to get an external thermal sensor.

My VNF3-250 and CG 3200+ with the oem cooler at stock speeds and voltage read pretty high as well. I think it was at around 58C idle and near 70C at load. This is much higher than my old CO core A64 3000+ on the same motherboard and cooling, which idled at 38-39C with the OEM cooler at default voltage. I cleaned the cpu and heatsink off and applied some AS5 and it dropped some to 54C idle and 65C load. I thought it might be the heat spreader's contact to the core so I removed it, but the temps only dropped slightly. Then I hooked up my watercooling and the temps dropped a little more to 47C idle and 52C load when overclocked to 2.55ghz and 1.7v. So I think that it is just reading the temps incorrectly. I'd still recommend you remount the heatsink to see if that may help some.

I am also having temp reading troubles with my VNF3-250 and 3000+. Everything is running stock, on stock cooling. In the BIOS, I'm getting a constant CPU temp of 49C, which i know is way high. I run SpeedFan on my desktop and I get about 42C idle and low-50s load. I think this is high too, as i have the A/C on and room temp is about 24C. I think it's just a BIOS issue, but I'm a n00b so I don't know.

yes its a bios issue
