Non standard CPU fan
Hi,
My CPU fan is failing fast - it starts at less than 600rpm and gradually works its way up to 1800ish RPM whereas it should run at 2500rpm. It gets worse on a daily basis. I've taken it out and cleaned it to no avail. I know I can oil it but it will only be a matter of time before it fails again. I'd like to buy a new fan BUT it's a very non-standard fitting. The whole heatsink/cooler unit is one of these http://tinyurl.com/yvh2wl (the link is to a shop which now seems to be out of business) and the screws are placed in a rectangular formation rather than square. I'm not keen to replace the whole unit as the heatsink is fine and I understand that there is some risk with this process but as I can't get hold of a suitable fan has anybody got any suggestions which may help me? Thanks, Kroma |

Here is what I've done from time to time. It works absolutely fine... but it's an add-ball solution. I remove the old fan and clean the dust from the heat-sink fins. Then a make a bracket from some spare sheet metal scraps... and mount a *case fan* directly above the cpu cooler with the air flow directed downwards toward the cpu. About 1/4 inch above the cpu cooler will do fine. (Fan bracket is mounted to the cabinet...usually in an existing hole) In the ones I've done...the fan runs slower (and thus quieter) than the original fan... yet has ...if anything...better cooling. I've had a number of machines running for many years now and have not had a problem... though I'll be the first to admit it may look a little funny! |

I've taken it out and cleaned it to no avail. I know I can oil it but it will only be a matter of time before it fails again. False logic. If you had oiled it in the first place, it might've ran just as long as it did the first tour of duty, and you wouldn't be risking complete fan failure by continually using it. Either lube it, or left the system turned off till you had a replacement. If you want to avoid this situation in the future, either buy a decent dual ball bearing fan, or lube the sleeve bearing fan next time instead of letting it run until it's dry. I'd like to buy a new fan BUT it's a very non-standard fitting. The whole heatsink/cooler unit is one of these http://tinyurl.com/yvh2wl (the link is to a shop which now seems to be out of business) and the screws are placed in a rectangular formation rather than square. It's an odd shape, but is it an odd dimension (width) or a standard 60 or 80mm, or less common but still obtainable, 70mm? It looks like it might be possible to attach a normal fan, with different screws or wire-ties to hold it down if necessary. It might require taking the plastic frame on the bottom off too. I'm not keen to replace the whole unit as the heatsink is fine and I understand that there is some risk with this process but as I can't get hold of a suitable fan has anybody got any suggestions which may help me? You can lube the current fan or replace it with closest size standard fan, there is nothing exceptionally difficult about what you're trying to do. If you lube it, use heavy weight oil not very thin and it will run for quite a long time, "IF" you hadn't let it run for so long like it was... so now it's life depends on just how bad it is, but any way you look at it, if you are going to keep using the system it should be lubed immediately, as a preventative measure until you can install a replacement fan or heatsink-fan combo. The situation you are facing is a good reason not to buy heatsinks that use proprietary fans. However, some of Arctic Cooling's products have a fairly long warranty, you might contact them and see if they can send you a fan if you want another one just like it - but frankly since it is failing and you dont like to relube it, it would seem better to get a fan that isn't subject to this short lifespan instead. |

I'm coming to the conclusion that this is my only option now. Maybe I could take the current fan to bits, saw the 'frame' down to half the width with a hacksaw and attach a new case fan to it (with electrical tape?) then, create a sandwich of old fan frame - new fan - heatsink? I may need to chop off a few bits of the new fan frame to allow space for the screws though. This way I can put the screws in their current places. It will look funny but I don't mind - hopefully the case will remain firmly shut until I next upgrade my memory. Kroma |

I didn't fit this, it came with my PC. I've never had to upgrade, swap or even touch my cooling system before and there was no warning that it had started to fail (no noises or anything) until my motherboard started to warn me.

I have contacted Arctic and they pointed me to an ebay store of theirs. Unfortunately, it lists many fans but not this specific one. Kroma |

As long as it works, that's all that matters however it would not really be all that big a job not too expensive to just replace the entire cpu cooler assemby with a new one -- Posted via a free Usenet account from http://www.teranews.com |

I have contacted Arctic and they pointed me to an ebay store of theirs. Unfortunately, it lists many fans but not this specific one. Did you measure the mounting dimensions? Like I wrote previously, it's probably a standard size, just an unusual looking frame, so a standard fan might work fine, merely needing different screws "maybe" (It's hard to tell from the linked picture as it isn't very good nor very informative). |

Hi, My CPU fan is failing fast - snip I'm not keen to replace the whole unit as the heatsink is fine snip the heatsink itself - a chunk of metal, doesn't normally fail. Not to my knowledge anyway! Why exactly don't you want to replace the "whole unit"/HSF? Replacing the HSF is standard procedure. Personally, i'd probably buy a new one than even go through the hassle of oiling the thing! Infact i'd probably have bought a second one initially anyway as a spare. And MAYBE oil the broken one - for fun. What do you do when your hard drive or motherboard dies? get out a soldering iron? More power to you if you can do it. But how long does it take? 10 hours ? 2 weeks? a month of sundays? |
