Best heatsink for SiS 735 chipset?

well my computers been crashing and I found out it's because of my northbridge/southbridge (it's 2 in 1 chip) has been overheating...and so I got a ecs k7s5a based off of the sis 735 chipset...I put a 80mm fan on it and after that no crashes...so anyways...what's the best heatsink? I don't need a fan because I'm not doing any oc (obiously...look at my board)...I just need something that'll cool it...and the reason I say heatsink only is so that it won't produce any notice....any suggestions?
 
I had no problems whatsoever with the stock chipset heatsink at 133/133. A while after I had bought the board I stuck a Crystal Orb to it, but I haven't noticed any more stability. BTW, the Crystal Orb is a tight fit on the chipset because the nearby capacitors almost block the two prongs.
 
Most people seem to find that removing the original and resticking it down with AS thermal Epoxy is often enough (the Frag tape they used is useless) and if not, put a 486 fan on it, this helps also with the warranty as they won`t take it back if the HS has been replaced with a third party one..

If Heavily OCing, try a leftover big 486 job or a modded Pentium-1 one, I can`t see a need to spend out on a GFX Card Hs/Fan - if you`re having probs at stock speeds, I`d look into your case temps and see if there`s a prob there
 
I thought the northbridge on the sis735 was supposed to run extremely cool. Or at least cool enough to run with a passive heatsink. I ran the k7s5a fine at 133. The heatsink was not even hot compared to the via northbridges.
 
Check out the Zalman chipset heatsink kit from 2cooltek or Siliconacoustics- Not a bad deal if you don't already have thermal epoxy.
 
I don`t get probs at 138/138 with the stock heatsink either and the chipset IS cool compared to a VIA - BUT the main reason why no heat whatsoever can be felt is that any produced is not getting TO the heatsink, remember folks, a warm heatsink is a GOOD thing, it means the thermal interface is doing it`s job.. Bring back the days of them using sprung clip heatsinks like the BX boards had 🙂
