Just did a post on cooling in the mods section. Might be worth a read.

Arctic Silver's "Arctic Alumina" is an example of a thermal adhesive (thermal epoxy). Most electronic parts shops should have something similar as well.
But it is cheaper (and easier to find the materials) to just use ordinary CPU heatsink paste and a drop of superglue in the corners. Loctite would be fine. Look for the word "cyanoacrylate" on the package/tube. |

I actually tried OC my computer, uses that CHSFB program, at the minute I have a Duron 1ghz, I tried setting the FSB/DDR to 110/110, it boots but when it comes to the boot prompt for windows 2000 (the sort you chose which OS to run) it would freeze. Would getting rid of the adheisive and using a proper glue, would this fix the problem.

That sounds more like the CPU that doesn't like the overclock.

It may have been said before, but it may be a nice addition to add a small fan to your heatsink on your chipset. I found the perfect fan sitting in my parts box as I erad the first page of this thread. It would mount perfectly with some small screws that would bite in between the blades on the HS. Hmmmm...

Do you use the copper looking heatsink that comes with the mb, or do you use a differnent heat sink.
On a side not i remembered that My heatsink on my CPU is a sticky adhesive, it was a coolmaster one, could that be a reason why it does not like runing at 110/110? -ali |

The standard heatsink is made of aluminium that is anodized yellow. It should be fine in most situations if attached without the double sided tape. However, if you want to be on the really safe side (or you are overclocking), it can be a good idea to use a bigger passive heatsink, or one with a little fan.
On my boards, I use Zalman high-profile passive chipset heatsinks (This one and This one), But any old 486/pentium style heatsink profile should be fine too. If your CPU heatsink uses a thermal pad or something similar, you will get noticeable better (lower) temperatures by scraping/cleaning it off and using a thin layer of thermal paste instead. |

Have just done this mod,(and additionally fitted a small fan to the heatsink).I found the best for removing the old sticky tape goo from the heatsink was ordinary electrical switchcleaner.

Just wanted to throw in my rambling two cents here: Try PLUMBERS GOOP rather than superglue to mount a new heatsink to the chipset. (it is heat resistant, but has a little give) You will be able to upgrade the heatsink on your chipset in the future or RMA it because you can remove the heatsink easier to switch it back to it's original configuration. Superglue breaks down from heat and there is nothing worse than a heavy heatsink with a fan mounted on it falling off and taking out your graphics card in the process. Also if you put a dab of plumbers goop on each screw hole where fans mount to your case, then attach the fans with the glue and leave out the screws it makes the casefans much quieter because there is nothing transmitting vibration. All my fans are attached this way.
Also, if you lap the 486 or PIII heatsink with some fine wet-or-dry sandpaper 600 grit or higher until it is really shiny, this will give you almost five degrees better cooling from personal experience. Also WD40 or a product called Rapid Remover takes the old adhesive right off - just remember to clean both surfaces with alcohol to make sure they are totally clean before gluing ........ |

Plumbers goop, like automotive goop, household goop, is a clear NON-silicone based adhesive/sealant.
Thats important because (unless using automotive sensor safe) silicone releases copius quantities acetic acid (ever notice the vinegar smell) while curing. Any local or online hardware store should stock it. Ace, home dumpo, lowes etc. Its alittle more expensive, but very good product. I would suggest the auto goop, as apparently withstands higher temps... Hullujua nuo Suomalaiset!

I just upgraded from my AMD K6-2 500Mhz to the K7S5A and a Duron 1.1Ghz Chip. I first thing I noticed with this board is the monitoring software on the CD doesn't work.
I also noticed the stability issues above. So I took my motherboard out... I sat down at my coffee table and modded the hell out of it. I took the heatsink of, cleaned it with some alcohol and put the lil orange heatsink away. I broke out my old K6-2, took the heatsink and fan off it. Took the fan off the heatsink and took the clip off (the one that "straps" it to the cpu). Then, of course I put it back together. I glued it down, with some thermal epoxy and hot damn... it hasn't hung yet. It's been running for almost a month solid now. I also stuck a probe there (that sounded bad) for a bit to see what it was running at... It sits at 4 to 5 degrees above room temp. Not bad at all. |

I've read over this and have decided that it's my next fix since updating the BIOS did nothing. After I've removed the heatsync and cleaned the tape off of the chipset and heatsync, do I have to apply anything to the chipset itself or just to the corners of the heatsync to get it back on the board?

Thermal paste in the middle, daps of glue in the corners.

I've read through this thread and other posts, but not found if anybody has used 'Methylated Spirit (mineralised - methanol content not more than 11%) to clean the chipset. Will this be ok?

Based on this thread, I replaced the tape with heatsink compound as suggested. I ran the Prime95 torture test before and after, and I can not tell any difference in the temp of the heatsink. It has never felt very hot. The cooler on my boxed AthlonXP 2000 blows air out the sides (i.e. toward the chipset heatsink) so that might be helping to keep it cool. The tape that I scraped off did not look like simple double-sided tape as others have suggested. I would guess that it was some kind of thermal tape, but I could be wrong. My board is a brand new Rev 3.1 if that matters. Note that on my chip it had two layers of the tape. The chip and/or heatsink was not very flat. I had to put a thicker layer of heatsink compound in the center of the chip to fill the gap.

Bump. This is an interesting thread... I need to re-read it when I get home to my K7S5A.

My new machine:
Retail version AMD XP2000+ with fan K7S5A 3.1 bios 02/08/09 1 bank PC133 RAM 512M IBM 45G HDD BTC CDRW 40X12X48 Geforce 2 MX 300W PSU WINDOWS 2000 PRO The system is running at 133/133, the cpu idle temperature is 55-56C, case temp is 35C. If I do mpeg4 encoding(100% cpu load), cpu temp goes up to 64-65C, sometime it just freezes after 10-20 minutes in this state. Questions: Is my system too hot? Is the chipset heatsink problem? Is the retail version fan problem? Any suggestion is welcomed, I still have 3 days left to return it. thanks. |

Your CPU is definitely too hot, and your chipset could be too hot.
Normally, the retail CPU heatsink/fan should be able to cool good enough, but you could have a problem with too high case temparatures or that the heatsink doesn't have proper contact with the CPU core. |
