cimo Posted January 9, 2008 Report Posted January 9, 2008 i was rather surprised to see how hot the 6582s can become, what is to be considered normal? heatsink would be an option?simone Quote
bugfight Posted January 9, 2008 Report Posted January 9, 2008 in my mb-6582, the sids get pretty hot.uncomfortable to touch, but not painfull(make sure you don't discharge static electricity if you try this *whack*)i picked up some heatsinks that are almost the right size, but don't have any cement to glue them down yet, so i run the loud fan, which helps considerably Quote
cimo Posted January 9, 2008 Author Report Posted January 9, 2008 uncomfortable to touch, but not painfulljust like thati picked up some heatsinks that are almost the right size, but don't have anycement to glue them down yetJB (not the scotch whysky) Quote
bugfight Posted January 9, 2008 Report Posted January 9, 2008 ...JB (not the scotch whysky)jb weld?? no way!i'd prefer the JD...or maybe some stain *whack* Quote
Wilba Posted January 10, 2008 Report Posted January 10, 2008 I have considered a semi-permanent solution...PC RAM heatsinks (conveniently 8 per pack)http://www.performance-pcs.com/catalog/index.php?main_page=product_info&cPath=43&products_id=21310Theoretically, you could solder a piece of copper wire to two edges of the heatsink, then wrap the wire ends around the SID and twist together underneath to tighten it. Use of a thermal compound is required, but I would not bother with the expensive silver stuff. Quote
Nestle Posted January 10, 2008 Report Posted January 10, 2008 is it like they are more hot than the other SIDs? I have several running at the moment and hadnt had any problems with the heat. So, if these are running hotter, maybe I should glue some on them too.Is there anyone who can compare the SID temperatures?Nestle Quote
Wilba Posted January 10, 2008 Report Posted January 10, 2008 6581 gets hotter than 8580/6582.I would say 8580/6582 get "warm" and 6581 get "hot".It should not be a problem if you have a ventilated case (i.e. some holes to let warm air escape).On the topic of heatsinks, in one C64C (beige case, not the old brown case), it had a 6581 in it and a huge metal sheet that made contact with the SID (and some other chips I think) with some thermal compound.

cimo Posted January 10, 2008 Author Report Posted January 10, 2008 hiTheoretically, you could solder a piece of copper wire to two edges of the heatsink, then wrap the wire ends around the SID and twist together underneath to tighten it. Use of a thermal compound is required, but I would not bother with the expensive silver stuff.i ve already considered this method but with a little variant:bear with me now (and with my english)you need a "tightening strip" which in my personal language means that kind of plastic strip (usually black or white) used, for example to tight a bunch of cables together, it has dents and a squared hole where you push in the tip of the strip.Are we there? good.Under the IC sockets there is usually space enough to slip the "tightening strip" underneath and loop it on the top so you can press the heat sink against the IC.uh?simone Quote
bugfight Posted January 10, 2008 Report Posted January 10, 2008 ...you need a "tightening strip" ...zip ties.don't forget the thermal compound though.i'm thinking a thermal adhesive would be best.also i think it's important to find heat sinks that contact the whole top surface of the chip. Quote
cimo Posted January 10, 2008 Author Report Posted January 10, 2008 ok i got the heat sinks the zip ties and thermal compound, it just works great!!i will show a pic whenever a cam will visit my housesimone Quote
dj3nk Posted January 10, 2008 Report Posted January 10, 2008 For some parts of my pc I use regular heatsinks. A LITTLE BIT thermal compound on the middle and some second glue on the edges.This is a 2 component thermal glue. I glued the heatsink of my graphic adapter and its really like a stone !! I dont think i will ever get it away.http://cgi.ebay.de/Zalman-2-Komponenten-Waermeleitkleber-zum-Top-Preis_W0QQitemZ310012749311QQihZ021QQcategoryZ78803QQssPageNameZWDVWQQrdZ1QQcmdZViewItemgreetz Quote

I was originally going for more robust solution, but seems I go for this one, almost same than yours :)35,6x22x6,7 mm Heatsink(don't change to english or you get wrong specs (of peltier element but with same product code/picture :o) Quote
cimo Posted January 15, 2008 Author Report Posted January 15, 2008 hithe pitch between each sid is about 22mm (wilba can you give us an exact measurement?), those ones you showed are 22mm so they should just fit.simone Quote
Enth Posted January 15, 2008 Report Posted January 15, 2008 Yeah I took a look at base PCB and it seemed a really tight fit. The pitch between each sid for me seems like 23mm so I have generous space to work with ;D And I can always modify the legs by bending the legs up earlier, or cut every second one off... Quote
Wilba Posted January 15, 2008 Report Posted January 15, 2008 900 mil = 22.86 millimeters(or 0.05 cubits if you prefer) Quote
Enth Posted January 15, 2008 Report Posted January 15, 2008 Thanks for the info, that should be enough if the heat sinks really are <=22mm wide. Quote
cimo Posted January 15, 2008 Author Report Posted January 15, 2008 just be sure that that is the overall measurement and not the base measurement, have a look in the datasheet.simone Quote
