Opteron 175 too hot!

So I just replaced my old 3500 Venice in my A8N32SLI with a brand new Opteron 175, but I can't figure out why temps are so high. My old proc used to idle around 36c with load around 43-44c, but this new proc idles around 45-46c. I've reseated the heatsink twice, the first time using AS5 instead of some el cheapo stuff, and the second time I tried a different application method for the AS5, but none of these have changed temps at all. I've dropped voltage as far as I can and remain stable, down to 1.2625v in the BIOS (which, on this screwy motherboard, translates to about 1.31v).

I'm using a Scythe Ninja heatsink and normally I don't really care too much about temps, it's just that this motherboard has quite possibly the worst implementation of Q-fan I've ever seen: it doesn't have any settings besides on or off, and just brings the cpu fan down to about 5 volts until cpu temps reach 46c, then it ramps up to full speed (12v), which is extremely annoying since I'm idling around this temperature, so my cpu fan keeps going up and down from about 900 rpm to nearly 1600rpm, which is really loud to me.

I was under the impression that Opteron processors ran really cool, are they really that much hotter than a single core venice? What else can I do?
 
the ninja should be doing better than that. i have it and i idle at 36 (its hot as hell here) and about 28 during the cooler months. this is with my overclocked 4400
check to see if the base of the hs is flat. otherwise im not sure.
 
are you overclocking? what volts are you at?

also use speedfan not qfan

speedfan can control your fan header.....

also X2s will be hotter than single core chips.... but i agree that is a little warm.

what case are you using and how is your air flow?

also what fan do you have on the sythe ninja?
 
dont use speed fan, it blows (no pun). use coretemp. speedfan has a habit of misreading and mixing up sensors.

However, coretemp has some compatibility issues. I cant run the newest version on my opty165 and NF41 motherboard. It reboots my system either immediately or after a few minutes. I can run .94 though. Right now with the hot weather mine idles at 46 for one core and 38 for the other. Under prime with about 90 degree weather, under load hits about 63 and I dont have any problems. No reboots or anything. What are your load temps?
 
My case is a Lian Li PC-7B and I have it built for silence. I have one Yate Loon fan as intake running at 5v, and I have thisArctic Cooling fan for exhaust and the "normal" version of it (the same fan, just with a standard frame) on the ninja. Both are attached to the CPU fan header on the motherboard using a y-connector, so they're both controlled by Asus Q-fan (usually running between 700 and 900rpm). I know it's a very low airflow setup, but my old venice was running about 10c cooler under the exact same conditions.

The voltage is as I said earlier, set as low as possible in the BIOS at 1.2625v. This motherboard seems to overvolt the processor by a lot, so cpu-z reports voltage to be about 1.31v.

Coretemp may be more reliable since it's currently reporting temperatures at about 38-40c idle, but the motherboard senses temps differently and speedfan accurately reports temps from the BIOS (which is what is controlling my cpu and exhaust fans) as 45-46c. Load temps (from playing counter strike) have reached above 50c, but I don't think that was putting full load on both cores. How do I do that on a dual core anyways?

Bottom line, my BIOS is reporting really high temps (which may or may not be accurate) and is screwing with my fan control setup, which is what is really bothering me.

Edit: also, I'm not overclocking. Running at standard 200mhz fsb with 11x multiplier.
 
Wow that without an overclock? I idle at 32 without an overclock but i do have the IHS removed. I dunno, try an manual speed controller if you dont mind. This way you can disable QFan and adjust the speed as you please. Load temps of 50 degrees is still ok. Its anything above like 65 where you should start worrying.
