I would try to keep it uner 75*C for 24/7 usage. Although 80*C would be fine for a suicide run. You shouldn't be able to kill anything as thermal throttling would occur at high temperatures.

Regardless of whether or not Thermal Monitor or Thermal Monitor 2 is enabled, in the
event of a catastrophic cooling failure, the processor will automatically shut down when
the silicon has reached an elevated temperature (refer to the THERMTRIP# definition in
Table 25). At this point, the FSB signal THERMTRIP# will go active and stay active as
described in Table 25. THERMTRIP# activation is independent of processor activity and
does not generate any bus cycles. If THERMTRIP# is asserted, processor core voltage
(VCC) must be removed within the timeframe defined in Table 11

Coffee, just looked at your case pic. How much did the Typhoon give you over the AC 7? I'd put the AC 7 back in personally, it would create a good front-back airflow in the case. The typhoon might be disrupting the airflow causing overall bad than good. Just a thought

It was about the same. I can try it (not today - knackered). I do have a 120mm blowhole on the side of the case to draw fresh air in (although I don't have enough room to install a fan there). I'll give it ago though.

EDIT: I forgot, I couldn't mount the AC7 properly because of the silly IP35-e northbridge. so I couldn't have it pointing the 'right' way. So it disruped airflow all the more.

EDIT2: The processor will throttle and shut down at 90*C despite the fact that it can be taken to 100*C. So 90*C is the absolute max. SOURCE

Are you certain?

I've run my E2140 (400x8, 1.376v, Zalman 7700Cu) within 10-15C of the tJMax for litterally thousands of hours with zero ill effects. Utterly no sign of damage or degradation. It's been running for almost a year, nearly under constant load at those speeds and settings.

I also had a second E2140 that I also ran within 15C of the tJmax for extended periods of time. Again, so sign of problems.

I always though the tJmax on them was 85C, btu even if it's 100C, distance to tJmax is what counts, and as long as you are below that, you should be safe, unless you are pushing excessive voltage.

If the tjmax is 100C, then I was running 85-90C at times, with no throttling (and yes I know how to check).

Also, I've never heard of a processor with a thermtrip below the tJMAX. That wouldn't make any sense at all. I don't think the tJMax can be 100C on these chips.

Well, I agree with you on the whole. Running at high temps will likely cause less damage than running at very high voltages. From intel themselves, the thermal trip is set to come in at 90*C. If Intel just relesed the actual TjMax it would make everybodies life alot easier. The TjMax is assumed to be 100*C because of the M0 stepping.

Its all intel has to say on the matter. Page 84 is what you want.

I'm assuming you mean it was turned so that it blew up/down, and not front/back?

yeah. the fan assembly hit the norbridge heatsink so it was impossible I had it set up so it exhausted into the PSU (bad for the psu though)

Could you spin it around so that is blew to the front of the case? Then switch the wiring on the fan so that it pulls rather than pushes?

I never thought of doing that, although I think fan blades are set to a pitch to work efficiently one way. May be worth a try. I modded an 80mm fan to give a pull push configuration - very noisy but it gave a 2*C temp drop.

Page 84 is just an example. It says right on it that it is not meant to depict an actual implimentation.

Page 71 also states that the THERMTRIP is set to approximately 20C above the tCASE (which is 61.4C on the E2180, according to table 28).

Given than the tC and tJ should be reached at the same temp (on-die temps really are 20-25C warmer than the top of the heatspreader), the THEMTRIP should not be reached untill atleast 105C, or 120C if the tjmax is really 100C.
