| silent cooling of the northbridge of a Abit KR7A Hallo I am trying to silence my system, I have installed a Zalman CNPS 6000-Cu and the most silent 80 mm papst fans and I have discovered that the tine little fan on the northbridge of my Abit KR7A makes a lot of noise. Does anyone have a solution? Zalman had a special heatsink for the northbridge is it any good? Should I replace the 40mm fan by a silent one, which one do you recommend? Also I think that fan on my Abit mobo is fastened by 2 white plastic pins, can the heatsink and fan be removed easly, does anyone know if abit glues the heatsink to the chip? I do not use my mobo for overclocking, silence is what I want. I will be replacing my Radeon 64 MB DDR Vivo with a Hercules 9700 Pro as it is equiped with a silent fan. Thanks |

| the fan an the northbridge is not that system critical so if you dont overclock , you can just remove it. (only the fan!) |

| hi there did that mod this week: -zalman passive cooling, mounted with velcro screws. those crappy, standard springs don't press enough--> after attaching & removing for testing, the middle piece made barely contact with the NB -stock 40mm fan of the KR7A mounted on top of it, but at 5V mobo tray isn't mounted in my case, just on it's side (like a workbench) with 2 120mm's @5v blowing on it @FSB 180+, the heatsink doesn't get really hot so it's okay when removing stock hs/fan, be very careful: you have to press the end of those push pins together, and then pulle 'em out mobo is 2nd handed, and one of the tips of one of those push-pins was b0rked. had lotsa trouble removing it, and I've made a scratch with a plier on the PCB; no circuits were harmed so it's working fine now |

you really think a tiny heatsink of 0.5cm high will cool the NB sufficiently? you even think abit would mount a powerful fan on it if it were useless?? | |

and on my epox there is no fan on it and it still works well. as Abit is made for overclockers (i suppose) they cool it with a fan. i really can't see the harm in removing the fan and just let the heatsink cool it. also a fan of 1CFM doesn't makes the difference in my eyes. kind regards | |

besides, NB heatsink with 0CFM --> 1CFM is a bigerg difference then you would think | |

| Well it seems that i will not have to replace the fan of my northbridge, I disconnected te fan of my ATI Radeon Videocard and the whining sound was gone. So I will have to replace the fan on my videocard. Does anyone have recommendations for a silent videocardfan for Radeon 64 MB DDR VIVO (AKA 7200). The card has no holes so Zalmans solution is not an options. Soon I will be replacing this radeon with an Hercules Radeon 9700 Pro, Hercules claims it has a silent fan. |

| if you want to go "lowcost", change a socketA / socket7 cooler to fit your vidcard & place a silent 80mm fan on there!
