What's a good "Delta T"?

[maxwell1295]

The delta between my motherboard temp and CPU temp is usually about 12*C. I'm not sure whether that's good or bad. Is there a 'norm' for something like that? My case is aircooled and CPU temp is normally in the 36-38*C range, with the motherboard temp in the 24-26*C range.

delta t

I'd put a thermometer on your desk and use the ambient room temperature to compare with your cpu temp. Then put the thermometer in a couple of different places inside your computer case and use the average case temp to compare with both the room temp. I think those delta's will be more meaningful.

You want the smallest delta you can get between ambient air temp and case temp. And the delta between the ambient air and the cpu should be 8-20 C depending on your cpu and cooling.

10c is a good delta.. thats roughly what my water cooling gets..

Thanks for the info. I'll get a thermometer and try that. The room is fairly warm, but I have no idea of what the exact ambient temp is in here right now. All I have to rely on for temps is MBM5, which pulls its readings from the BIOS. I have no idea whether the mobo BIOS probe is accurate or not.

Now, about that 10C delta.....is that between the mobo ad CPU or ambient and CPU?

room temp, and the cpu temp.

There is another parameter that hasn't been included here. Load or no load. A good air cooler would usually achieve a delta of 15-20C under load and water around 10C. An unloaded delta is a useless parameter.

10C is very good even for water. I get around that. My record is 7C with an enclosed case in a very cold room.

well my load delta is around 15, cuz i have a crappy rad and a very hot room..

delta

11 to 18 C is my delta, depending on idle/load.

You are aircooled though. My specs were full load with water cooling. Most of us were talking about water I think. Pretty good temps I guess.

yea thats pretty good for air..

air temps

Yeah, air cooling is what maxwell1295 was originally asking about. I think 15-22 is probably the delta most good hsf's will get when comparing load cpu temps to ambient air temp.

well i guess when i think of overclocking i tend to think of watercooling too
