E6400 - P5B Deluxe overclock temp questions - Page 2

post #11 of 12
Thread Starter 
Thank you for the answer.

I do find that all the temp monitors don't agree and I do know the differences between CPU temp, core temp and case temp. I notice that MBM5 and ASUS Probe seem to match and the TAT always gives a lower temperature (usually 5C or more). The Core Temp program seems to be closer to TAT.

The difference between Arctic and Tuniq is more like $40 and I was just wondering if that difference was really worth it if not going to extemes. To me good enough is quiet and cool enough to not damage the CPU while getting more than out of box speeds. From the way the temps drop when I unload it and the idle temps, it appeared to me that the thermal load is just a bit too much for the stock HSF and lowering VCore helped a bit. My E6400 box says max 1.325V, I see posts of people going higher - what is the real limit? I want to keep it down if I can.

On a scale of 1 to 10 with stock being 1 and the tuniq being 10, where would the arctic be? 2? 5? where would the BT be? and the zalham 9500?

BTW I've been OC'ing since the good old days of the xtal mod to the old IBM XT that upped the clock from 4 to 6 MHz (wow a 50% overclock!). Now-a- days 200MHz is lost in the wash.

It depends on what you are doing with the CPU. With Gaming and a moderate overclock I would put the Arctic cooler at 5 - 6. With full load temps such as video editing of hour long events or folding on both cores whilst using the system I would then put it at 4 - 5.

I would put the BigTyphoon at 8 - 9 and with the cooling of the motherboard that the BigTyphooon also brings (~5 - 7C cooler) I appreciate it more than the Tuniq but that is a matter of preference. I can't speak to the Zalman as I have found the ones I did test were not up to their competitions abilities and so quit testing them prior to the newest ones.

It depends on the Chips with regards to limits of voltages in undervolting. Since these chips have a multiple VID (Voltage IDentification) and different stock voltages it is a different plateau (both ways) for these chips. You need to perform your own documented analysis to be certain where your CPU stands. Core temp will tell you of your baseline VID and then you can dummy down the core voltage after finding your sweet spot. You can do this with the stock cooler as the temps at such durations will not hurt your system. Thermal throttling will take over if any extreme issues occur.
