Clock gen. cooling

[KILLorBE]

Hi, Merry X-mas

I'm looking for some suggestions:

1 what kinda HS should I use, I was thinking of a 486 HS but the base is pretty thick ~1/4 Inch (6mm) I also have a PI HS which has a thinner base (2mm) and looks cool too (blue anodized).

2 How should I attach it?
.1 Super glue on two corners and some ASII
.2 Two component glue mixed with generic goo

I never had problems with the clock gen., but I'm thinking that it is holding me back.
Unlike other owners of a P3V4X mine never got warm, but I tried to get it higher today and it hangs or I get some other strange things (Invalid system disk, 264Mb:confused: , Lock-ups in BIOS).
I've tried several things like removing some memory, less aggressive mem settings and flashed BIOS to 1006 beta2.
All to no avail, I know it can run @900 (150 FSB) cuz I had it running at that speed (~90% stable, ran F@H for a couple of hours but when I tried to run F@H+3DMark2k1 it crashed).

Anyhow I just thought that I had to touch the clock gen. to see if it was warm, and yes it was warmer then ever before:p

BTW: I had the same problem with a PIII 733, it ran @ 825 (150FSB) for a while but I never got it higher, and after I changed the HSF and memory I could only get it running @ 814 (148FSB).
mmmmmm....makes me wonder if its the board, maybe that's why the newer P3V4X's are limited to 150FSB (Mine is old and goes up to 166FSB).

Any ideas?
TIA

BUMP

anyone?
sorry for being impatient:eh?:

I saw some two-part AS2 thermal epoxy at SVC, I think (link (http://www.svcompucycle.com)).

This Tennmax lasagna usually sells for $18-20 and makes a great clock gen hsf, Lasagna for $3.95 (http://www.mpja.com/product.asp?product=12813+FN)

On my P3V4X I used a Radio shack Ramsink (http://www.radioshack.com/product.asp?cookie%5Ftest=1&catalog%5Fname=CTLG&category%5Fname=CTLG%5F005%5F007%5F004%5F000&product%5Fid=276%2D1368) That costs $1.59 and it worked very well

Affix either with Arctic Silver Adhesive or Arctic Alumina adhesive

I tried cooling the clock generator once. Too bad my board died (unrelated) before I could test it. The Radio Shack Ramsink is good if you don't want to spend the time cutting up an old heatsink. The lasagna would probably be too big and hit something. The Radio Shack ones look about the right size to me.

If you don't want to buy anything, I'd reccomend you use the 486 Heatsink so it can dissipate the heat better. Since it won't put out a whole lot of heat, you might want to consider the PI heatsink for the cosmetics. For attaching them, any of the methods you stated will work. The AS and AA Adhesives would work as well if you wanted to spend the money

[Yodums]

Ramsinks would be my choice good cheap and efficent.

Although try to mount both on :)

Are you sure your CPU is not overheating? Or are you sure your PCI/AGP bus is too high?

[CrystalMethod]

I doubt the CPU is overheating. Cooling the clock gen. is always a good idea, actually isn't cooling anything that generates heat inside a PC a good idea? Been meaning to do it to mine but haven't had time with the Christmas rush gotta see if I can score some sinks from some of the completely dead mobo's in RMA. Hey, why pay for it when you can get them free, right?

Exactly, I got 14 of those 486 HSF's (bought them for the 40mm fans and they were about $0.60 a piece (cant buy a 40mm fan for that:) ), the actual price was $1 but since I bought them all I got them for half the price. I hear you thinking..."Bad math":p ,no I bought a couple of them the day before and had to pay $1, went back because I had some more ideas...2 HD coolers, GF2 MX cooler (just the fan) and today I thought I might as well put one on the southbridge (seemed to help some ppl), I've also put one of those fans on a Intel 486 100MHz overdrive chip...temps dropped a lot (probably from ~50-60C to 25C) I'll OC it just for fun and maybe I can run it at max. settings provided by the board (150MHz).

Another problem is that all shops are closed (most at least), And why pay when I don't have to, 14 486 HSF's, 2 super socket 7 HSF's, 1 PII HSF, at least 1 PI HSF, 1 stock Intel PIII HSF, loads of glue (all different for one of my hobbies...RC cars) and enough thermal goo for another hobby...electronics.

Well back to the subject, I doubt its the CPU temp (25C full load, F@H 24/7) PCI/AGP isn't a issue either, 37MHz now, but it runs fine @ 116/38.66MHz, @ 150 it would be 37.5.
I just thought it would be a nice day(12-26-'01) to do some modding, and I really want to get this old PIII600 cA2 SL3NL running @ 900 (50% OC:cool: ) because that's my goal, and I'll do anything to get it there (fry it when necessary:p ....good reason to built a new rig:D ).
When I have reached my goal I'll build a new system (gotta be nice to yourself when you've achieved something:D ).

Thanx for your replies, I'll cut up some 486 HS's and try to make thermal adhesive myself. wish me luck (probably don't need it, but you never know), I'm gonna do some major modding, 2 new fans in front of the case, HS here and there, make thermal adhesive myself, grommets between all fans (11) and make a fan duct out of alu. (with the peltier my case temp went up 3C+ (before it was the same as room temp), air coming from my PEP66 is 30C+).

a small ram sink should do, there are some nice copper ramsinks that should work very well and not get in the way of anything

I'd use double sided thermally conductive tape... It's a whole lot easier to apply and you don't have to worry about spillage. A little tip if you decide to go that route- clean the surface really well, tape the thing on there, hold it on the IC while you turn the pc on and let the IC get a little hot, then power the pc back off and let it rest for awhile. The tape seems to get better adhesion if it's warmed up and cooled off once under pressure. I'd also put your case on it's side (if possible) while it cools off. After I started doing that none of my misc. heatsinks pop off anymore.

[Colin]

The small HS from the Shack will be all you need. Every board I have tried one on has picked up 1 MHz FSB.

Epoxy would be better. Even with the best 3M tape you will have no where near the thermal transfer. If you use frag tape, clean both surfaces with Goof Off followed by IPA. Apply the tape to the HS, heat with a hair drier and bunish the tape. After it cools, peel the backing off the tape, apply to the chip with pressure and heat it with a hair drier.

[Hoot]

I don't get it. I just reached into my case and my Clock chip was cooler than my skin, with no HS on it.

Hoot, I had a P3V4X like KILLorBE has and it used to get really hot with a mild o/c After I put on that radio shack sink and that in turn got hot so I knew it was doing its job.

The Sh6 I got from Skip doesnt have a hot clock generator so I guess we should all praise the mighty overclocking Gods.


PS if your clock generator got hot I can only imagine what the heck you would devise to cool it, as it would be a job for a mini Hoot Shute :)


Happy Holidays bro!


ps whats with the 73 in your sig?

[TruckChase!]

Yah, for some reason Asus boards seem to be notorious for having hot-runnin clock gens. I got an extra 4Mhz out of my FSB with one of my older Asus boards. (Apollo Pro chipset i believe)

Maybe I'm thinking of the wrong thing. Might be the PLL I'm thinking of. I basically touch all the components in my system to see what's warm to the touch, if it is, I note it, and start looking for a HS for it.

CrystalM,

This is the clock gen. on a P3V4X
