Taisol 742092 Thermal Pad

Received the hs/f on 12/2 and now I'm waiting on the conductive pen to unlock the multiplier on my 1 gig T-Bird before I try it out. The heatsink came with a Chomerics thermal pad. Should I ditch the pad and use thermal paste?? I read somewhere that AMD recommends using thermal pad.

Thanks - Labman
 
Keep the thermal pad. As I understand it, that particular one is formulated to deal with the heat of that T-bird (eg., it does a phase change) and is AMD-approved.
 
Well from what I've read around here the general consensus seems to be that the pad is good enough to use and do some slight overclocking but if you are looking to really overclock then taking off the pad, sanding down and "lapping" the surface contact area and then using the appropriate amount of artic silver is best.
 
The Chometrics pad is actually pretty good for mild-medium overclocking. It does hang in their fairly well with AS, and definately better than silicon greases(which could dry up).

Thanks for the replies. I received the conductive pen today so I'll remove my "pencil trick" and apply a more permanent fix. I will use the thermal pad and if that takes me where I want to go then good enuff....if not, then I'll use paste.

Thanks Again - Labman
 
Crap, i forgot to say this, but remember to "cook" the pad to 58C in order to get it ot melt and fill microgaps between cpu and heatsink. Heat the cpu to 58C(won't damage chip) by disabling the fan, or simply blocking. Onceyour reading hits 58C, get the fan going again.

I find it odd that the pad has to be cooked artificially. Do you mean that normal operation does not give 58 C? That's a lousy engineering job. Whoever did it should lose his engineering license. (I am an engineer) There must be a material that changes phase at a lower temperature. If not, he should have put nothing on it and recommended (included) heat sink compound.
 
Yes, it's stupid.
But probably it they make it melt at lower temp, it will....melt away!
But he product spec sheet says reports its conductivity @70C.Product Sheet
 
i have found that the thermal pad that comes with the taisol is excellent, i noticed no differences in pre-60C heat up and post heat up. great interface material for the taisol.

 
Damm I didnt know that the Taisol comes with thermal pad I just ordered one and also ordered $14 Arctic silver🙁
 
I have the TaiSol 337092 I think, and I just left the pad on. Didn't even "heat" it to 58C. My Duron's running at 1gig, with temps in the 40's.

They perform better when cooked, even though the difference somtimes is small(sometimes under 2C Core Temp, which is usually unregisterable on socket A temp measurement methods).

The cooking is done so that the material "phase-changes(hence the PCTC name)" and fills micro-gaps between cpu and heatsink. And it does a very good job of this.


Mike
 
Thanks USUL for the link. But it does not say anything about the precooking or phase changing temperature. Where did you folks get that info?

I kind of suspect that the phase change occurs over a temperature range, rather than a specific temperature. (based on my materials engineering hunch, the area of my specialty) I would appreciate if someone could give me a lead so that I can get definitive information.

If nobody has that information, I can contact the sales department and ask that question as customer representing my company. That's an interesting piece of information that I can use at work down the road. Please let me know either way.
 
Mikewarrior2, and others.......

I just finally received a Taisol 742092.......looks really promising....but,..the machine finish on the bottom of the heatsink has left a surface consisting of numerous very tiny, but noticeable, uniform ridges.....
I'm sure that a flat smooth, shiney surface would probably be better, but if I lap it, I will destroy the thermal pad............is this ok....will the pad fill in the ridges and work ok?
Has anyone noticed the same finish on theirs..?

Thanks for the info.....
 
Yeah, I noticed the same of my CGK74092. I havne't had time to lap mine yet, since I prefer using Arctic silver(i tend to swithc heatsinks a lot, for fun 🙂).

if you're using the default pad, since the pad is fairly thicker, and definately thick enough to fill the ridges, you shouldn't have problems using the default pad.

If you do decide to take the pad off and use a grease, definately lap the heatsink base.

Buildingacomputer: I put all my knowledge in TaiSol in the review in my website. But still need some more data.
If you mail chometrics, please tell me what they say.

DaddyG got the info from Chometrics.

I believe the stuff phase-changes at 58C, but because of the nature of socket A temp measurment, it phase-changes at a 52-58C temp reading range.

I'm certainly not an expert on this. Ask DaddyG on either the Cpus/Overclocking forum or GH for some more specific info. I do know that the PCTC, due to the phase-change nature, does a great job filling gaps between cpu and heatsink, and also does a great job because it is heat-fused to the heatsink by the manufacturer.
