I have had my new heatsink(Zalman 7000A Al-cu) installed on my 2.6C for about 4 days now, with OCZ ultra 2. Now, It has been running at great temps, 26C idle and 35C load. I just went into my BIOS to see what turning HT off would do, and it raised the temps to 37C idle, 44C load. Now, So I obviously went into the bios to change it back and now my temps are about two degrees hotter than they were, 28~30C idle, 37~38C load. Whats up?
Way hotter than usual

prolly just the thermal grease. i wouldnt worry about those temps as i idle in the high 30's and full load in the mid 50's
2 things...
1) first off you have a great mobo for reporting cpu temps though I don't they are accurate....
2) There is no way you are fully loading this thing yet..... A 2.6c P4 is putting off about 75watts of heat and even with a zalman al-cu which I believe has a rating of .18c/w would mean you should experience in the ange of a 14c swing from idle to load.....You need to load this with an actual stress tester for a prolonged period of time to call it a load temp....MOst willassume when you say that it is a max temp for the system at 100% load....
If you mobo reports that then I seriously doubt you are looking at the right temp being reported or your board is seriously flawed in temp reporting....
I have a very nice cooler with a super high cfm fan (92mm) and I experience 20c swings still....7c??? I don't think so...
Not to thread crap just want to clarify things that bother me when ppl report temps....
temps being reported not only look great but look phenomenal even at the 2c higher temps...
Good thermal stuff like AS actually will not experience breakdown and actully gt a few c better after a few days...My AS2 could xperience a 2-3c better temps about 3-4 days later...MY AS5 only improved maybe 1-2c on average with general same room conditions...

AND, I have the Asus P4C800 Deluxe, in case that would help you help me. And OCZ ultra 2 is supposed to be great thermal paste....
Rechecked, idle is now 29C, load (now while running Sandras burn-in of cpu arithmetic and multimedia benchmarks) is 41C.
Burn is is not as effective of a stress and loading app as it is not thoruogh in testing all the registers of the cpu as well as continously...there are little lulls....
Remember also that HT is the true 100% effective way to tax the cpu so do one of these...
1)Run 1 instance of prime95 (blended test) and then also run SuperPi 32mb test...let that run for 30min to 1 hour and look at the test....
2)Run 2 instances of prime95....you start the 1 instance with the icon and then the second one you go to Start - Run -CMD - cd.. - cd.. - cd program files/prime95 - prime95 -a ..... This will launch a second prime95 aplication and start the stress test....You will notice that now in the task manager you will see 100% cpu usage....
In your MP2 program there is a good liklihood you are not running 100% but 50%...Check it out in the task manager...Pinnacle 8.8 for me only runs 54% during and encode...It is not HT optimised (much) or multithreaded...
3) You could run your MP2 app and start a prime95 test in the background...This will load it 100%
Load it 100% as verified continuously in ask manger and leav it there at least 1 hour but 2 if you can.....
1 instance of prime for me may load me at 57-58c and the 2nd instance takes me to 61c....Running SuperPi 32mb by itself and I go to 56-57c, but couple it with TMPGenc running and mpeg2 encoding and I hit 61c..Those temps are after awhile as well....
Asus is no surprise the culprit as many agree the temps are a bit low and many do not put stock in them....Idle temps are rarely that far off between most all brand s of heatsink...even the stock gheatsink and fan in an idle state can swing numbers close to 40 dollar aftermarket coolers...it is when loaded and temperature rises we see the effectives of the thermal capacity of the heatsink and the materials used, as well as the fan speed and subsequent cfm.....The stock fan I think has like a .23-.25c/w rating or so...Therefore the temp swings with your 2.6c at 75watts would be more in the range of 18c...As we oc them to 3.2ghz and about 90watts that compared to your al-cu design starts spreading to 6-7+ celsius difference.
The 12c swing is getting more realistic but I bet a nice burn-in of the options above will get you a few morw celsius over that....
