Conroe E6600 - How Hot is Too Hot?

[KungFused]

I have my new E6600 clocked at 3.0GHz (333MHz bus speed) right now, and Core Temp is reading 62ºC on both cores after about ten minutes of running Orthos. The temp has stayed constant here for the past few minutes, and doesn't show signs of changing. Assuming I get no errors in the next hour or so of stress testing, is that load temp too high? Should I cut back a bit on the overclock?

Thanks guys!

Is this on the stock Intel fan?

You betcha. 🙂

I'm considering getting an aftermarket HSF, though. The Zalman CNPS7700's look pretty snazzy. I guess the corollary here is, with load temps like that, do I need it?

Yeah that is hot - application of AS is key to S775 cooling. You need to make sure you have a liberal amount of AS in the center. The IHS on the 775 processor are concave. Ive seen my temps drop 10c to 15c depending on AS application.

62 for tjunction isn't too hot. There's a guide over in tomshardware forums here. Anyway, 40-65 is normal.

Tcase/Tjunction

--60--/--75--75-- Hot
--55--/--70--70-- Warm
--50--/--65--65-- N
--45--/--60--60-- O
--40--/--55--55-- R
--35--/--50--50-- M
--30--/--45--45-- A
--25--/--40--40-- L
--20--/--35--35-- Cool

ou are going to want to read page 79-80 of the processor specifications LINKY

When cpu power-draw is increased so is Tcase. Thermal Throttle will always kick in at 85C on Conroe and 100C on Kentsfield. Specifications state that running your cpu in a state of throttle over time will degrade the chip.

Tcase is .26x+43.2 where x is W of cpu usage. As x is increased so too is the temperature of the die.

That is why Conroe E6600 is .26(65) + 43.2 (16.9+43.2) == 60.1 or Tcase. It will be higher on X6800 and also Kentsfield.
tCASEMAX is 85 degrees, tCASEHALT is 100 degrees. These can not be disabled.

Again this is why Dell can release OEM C2D boxes that have core temps of 75-80 degrees, my Macbook with a Yonah DC is even higher than that running around 90 degrees C, but it is still below tCASEMAX for the chip which is 100.

Server market is also screwed if Intel is only allowing temps of 60. You know how hard it is to keep 8 cores in a blade that cool.
