Default Stuck Sensor - What to do?

Looks like I have a stuck sensor on my new q9550. Core #2 stays at 40 all the time. Doesn't budge from that number even doing Prime or OCCT. Other 3 cores are ok. Now I was planning on putting this Q9550 in a folding rig 24/7. Should I worry about the stuck sensor? What do you think?

Have you tried another monitoring program?

If you don't overclock, I don't think it should matter.

Depends on how high you push it, and how much of a risk you are willing to take.

I haven't seen a lot of CPUs out there which had much more than a 5c difference between cores, and the chances of a cpu having both a stuck sensor & a high split reduce those chances even more.

If it were mine, I'd "assume" that the core with the stuck sensor would report the same as the highest working core and go from there. That said.... as it's always been with OCing.... if you can't afford to replace the chip if it fries itself, you might not want to go that route. :)

Yep tried them all (hardware monitor, realtemp, coretemp, speedfan) and same. Also tried to "unstick" it by using prime95, occt and intel burn test but no program gets the temps past 44 (other cores). And I guess it needs to get by 50 to have a chance at it.

That being said, it passed Prime95 (12+hrs no errors), OCCT 10+hrs and Intel Burn Test several times.

Want to fold 24/7 (Rosetta).

Core#0 and Core#1 are pretty much the same at idle 28 or 29. Core#2 is stuck at 40 and Core#3 idles at 19 or 20.

That should be perfectly fine.... depending on what cooling you are using. If you make sure temps stay below boiling point, I say fold away!

I just can't seem to get the temps high enough to try and get that core sensor "unstuck". I've been testing now for a few days now and other that it works great. Core#0 and Core#1 get to 44 max when stressing. Core#3 to about 35.

However I'm still not 100% comfortable to fold 24/7. I don't have the time to RMA it to Intel as I've read that takes awhile. So I might sell it and let the buyer know that there's a stuck sensor. Someone else might be more ready than I to fold 24/7 with it.
