Case is a little on the small side (it is an Ultra ATX Case 16 inches high, room for the floppy drive and 3 cd drives. I have a large fan on the back blowing out. I did have a fan on the front but it wasn't making a drop in temps and unplugged it cause it was rattling. I might try to find a bigger intake fan for it though.
I didn't try changing the multipliers cause this mobo from what I have read doesn't do so well with higher fsb speeds and lower multiplier. I have lowered the voltage but the computer doesn't seem stable and it hasn't dropped the temps either.
Stability has been fine only 1 crash in past 3 weeks playing a game. Load never gets above 58C.
Thanks for your help!
With your temperature monitoring software, you're looking at the core sensors which should register higher than the legacy TCase sensor. The latter is reference for the Intel thermal spec. With something like Everest Ultimate [trial or licensed], you should be able to see the reading for TCase, although it would also show up in your BIOS monitor screen.
Small cases require more attention to cooling and airflow, if they limit intake-fan CFMs. [Some people argue that large cases leave pockets of air that warm up, but attention to airflow may make larger cases easier to work with.] In my opinion (and others may differ), you need to increase athe intake CFMs to overwhelm the exhaust CFMs. But this doesn't seem to be critical to your situation, if your load temperatures (core) average 58C and TCase <= AVG(core C's) - 5. The main question for me: "What do you use to stress-test and obtain load temperature readings?" Try "LinPack" [IntelBurnTest] for 2 iterations "maximum stress" to see how hot it gets. If it's below 75C, you're probably still "OK."
The idle temperatures would seem to derive from your case-airflow situation. That -- again --- is just my opinion. The Arctic 7 Freezer-Pro is popular, even if "not the best." For a 65W-TDP core such as yours, it should be more than enough.
Also -- is the Freezer's fan thermally controlled? That may also have an effect on your idle values. If your VCORE is the "set" value indicated in your BIOS, it is not excessive. And if it is the "reported" value (CPU-Z), it is also not excessive. The safe voltage range for that core is 0.85 to 1.3625V.
Meanwhile, you can probably capture a 5C-degree temperature improvement by lapping the processor IHS down to bare copper. Lap the copper heatsink base of the freezer pro so that it's perfectly flat -- for some unspecified improvement. [Lapping the nickel-plate off the IHS will assure that it, too, is flat.] Since the improvement over AS5 with nano-diamond thermal paste [try Innovation Cooling's IC-Diamond] is between 2 and 3C degrees for a core with 100W TDP, I'm banking on closer to a 5C-degree improvement if you scrape off the Freezer's thermal pad, clean it up with alcohol. So there may be as much as a 10C-degree improvement potential in your rig -- a cost in sandpaper, alcohol, and $7 worth of thermal paste.
