4080 with Arctic Silver 5

I've had my 4080 for about a year now and decided to clean the heat sink today. Glad I did it was pretty dirty. I didn't do enough research about thermal paste and just used some Radio Shack Paste. Now I've ordered some Arctic Silver 5 and will apply it when it arrives next week.

I've read enough threads about applying AC 5 so I think I'll be OK. My question is since I've applied the paste today Mobil Meter is registering my P4 3.0 GHz as only 2.43 GHz. Could I have done something to my P4? I'm pretty sure that it always showed it as 3.0 GHz.

Another thing, my fans aren't running all the time now which is good and my Lapcool 2 is working fine but my processor temps are going up and down more than before. Temps are ranging from 53 to 61 and the temp rises and falls a lot faster where as before it would slowly climb and slowly fall.

Any ideas on this behavior? Does it seem normal? I'm fairly new at this.

Will the AC 5 keep my temps from ranging as much and keep it generally cooler?

Now it's registering at 3.0 GHz and 3.03 GHz after a reboot

My 4080 clocks 2.43Ghz on battery, and "3.00Ghz" with a slightly inaccurate clock generator that tends to drift up to 3.03 on occasion too, so that seems entirely standard. My temperature tends to swing between 50c and 60c, which is indded a tad high, but thats how the fan control is set in the firmware.

PAPPP - Your'e right. It was clocking 2.43 GHz on battery and when charging was cloked at 3.0 GHz. Thanks

BTW - do you use the Arctic Silver?

I use AS Ceramique (ive always felt better about non-metal-based compounds, less chance of a system-damaging accident). It doesnt "lower the temepratures" since the fans are temperature-controlled, but it did make it so the fans are on less, even while doing intensive things like CS:S.

Well now I don't know if I should have ordered AS 5 or AS Ceramique.

Guess it's a personal preference huh?

Arctic Silver told me that both work well but AS 5 has better temperature performance.

I guess I'll try AS 5 and see.

AS5 does technically (by benchmark-style tests) perform better, and my preference toward non-metal thermal compounds is exactly that: personal preference. AS5 seems to be the "standard" thermal compound right now, and i havent heard anything horrible about it, so im sure AS5 is fine.

PAPPP - I've been monitoring cpu temps, probably a bit excessively, after I applied the AS 5 to my 4080 P4 and notice that idle temps didn't change at all. Still ranges between 50c and 60c. That's OK though.

My real question is while watching my cpu temps on MobilMeter I notice that every once in a while my temp will go as high as 65c before the fan kicks in, just at idle, no gaming or anything. Does your 4080 do this also or does your fan always kick in at 60c?

Sounds exactly like mine. Usually cycles between the Bios-set triggrers (60c on/ 50c off) and occasionally spikes to 64-68 (usually 65) seemingy at random. I imagine it is some sort of glitch in the fan control where it doesnt "notice" the cpu is heating up until the "high fan" trigger goes by or something.
