temp for t-bird 700 at 750

[TP]

I have a t-bird 700mhz chip in a ms k7t pro board. I set the FSB to run the chip at 750, but the temp was going to 42-45c. what is a reasonable range for this setup? i am still
using the thermal pad, but am going to get to radio shack this week for some thermal gue.
I am running the chip at 735mhz in the meantime, and its running usually at 39-40c. (i wish i wouldve waited to get the pro 2 board....arghh)

What Heat Sink are you using with that T-Bird? If it is the Taisol heat sink, replacing the thermal pad with Radio Shack thermal paste is actually a bad idea as that particular pad is very nearly as effective as Arctic Silver! Instead, what you want to do is disable the HSF fan temporarily (either unplug it or stick a pencil in it so it can't turn, and turn the computer on for a few seconds to allow the CPU temperature to get just over 55 degrees Celsius. This will trigger a change in the thermal pad which will cause it to 'melt' into the microscopic pits and ridges of the CPU forming a VERY good thermal transfer area. You may have a bit of difficulty removing the HSF after this, as it will be lightly 'glued' to the processor, but if you don't plan to remove the heat sink, this will be a far better option than the thermal paste, especially since it will never dry out, and the Radio Shack stuff dries out (and loses most of its heat conduction) rather quickly...

i dont remember what brand (but i will look at the box later), but its running at 5500 rpm. how do you know when it gets to 55 degrees (or is that just the estimated temp it gets to by just turning it on that way for a few secs)?

its a "coolermaster" HSF. the box says its a 4500rpm fan, but fuzzylogic says its at 5500rpm. it was just a $15 fan I got at Fry's. I shouldve done the research...it says its for any t-bird..

If you don't have the fan running, you can go into the section of your BIOS which displays CPU temp and fan speeds and watch until it gets to 55 degrees, then just shut off the computer and enable the fan again.

Since your HSF is a Coolermaster, I don't know if it will have the same effect, but I would guess probably not, since the Coolermasters generally aren't the best coolers, despite the name. In that case, you may well be better off to use thermal paste. (or just get a better heat sink... )

so, the taisol hsf is considered the best? how much could i expect to pay for it? it may be easier to get the taisol HSF rather than have to keep reapplying the paste. thanks for the input!

The paste isn't that good. I can attest to that. I've the FOP38 which runs a Tbird 950Mhz at 45 degrees at full load, 38 degrees idle. I've an Alpha Pal which uses the thermal grease and it hits 51 degrees for the TBird @ 850Mhz, 59 degrees at 1Ghz and 47 degrees idle.

That was after the grease dried out though. It was as good as the FOP38 when first applied.
