Replace 4850 Club3d fan with a 120mm: good plan?

[Herald85]

So, my sister has a secondhand 4850 club3d . The fan has gone bonkers and makes too much noise. Temps have risen as well. I'd like to help her out but I only have 120 & 140 fans. Before I drive over there, could someone confirm if this will work properly if I remove the stock fan and use zipties or velcrostraps to position a 120 over it?

should be ok just mount it close to the heatsink

80mm fans don't work very well on modern coolers, the closed sided fin design kinna ruins air flow over the fins and you end up having to compensate with a louder fan.

Tell her to order one of these ~> http://www.amazon.com/Zalman-Z-MACHI.../ref=de_a_smtd

When she gets it in the mail slide over and remove the old TIM, replace it with some new stuff and this cooler and you'll never have to deal with it again.

If she had any money she'd buy an upgrade instead of a 3rd party cooler
I'll just try the 120mm fan, if it fails then she can survive on bread and water for two weeks and buy a new GPU!

No money? She must not be very attractive .... ya'know that's a pretty nice 2500k ya got there . I'd be a good brother and spring for a cooler!


This isn't OT, we don't troll the OP over his sister and your opinion of her outward phenotype.

Kinna like how we're not supposed to suggest people are trolling yeah gottcha, all the sudden you got a rude mouth for a moderator cuttin down all the people you do. Keep it up.

It depends. If her card is like this -

Then airflow wont be impeded by placing a new fan onto it at all. Infact a 120mm fan will fix it right up and I would try it. The above is a Club3d 4850 btw but the designs vary..


You are probably thinking of the current standard which use "shrouds", and in that case a new fan wont help much. The bottom card is the stock 4850 which has the shroud design [and it sucked royal ass, I had one before].

I had two 4850 fans with the S2 coolers on them. I modded a 120mm fan on each. They ran cool and overclocked like crazy with them on.

When I wanted to remove the loud small fan on a card, I took an old PCI NIC and used a heat gun to remove all the components, then cut a circle in it and mounted a 92mm fan. The PCI card edge and bracket hold the fan nice and secure under heatsink, and using a much larger fan let me run it really slow and quiet. I don't see any reason you couldn't do something similar.

It's just personal preference, I'd much rather grab a sink more capable of displacing the heat almost entirely itself rather than let my GPU reach unnecessary temps on a lousy cooler with a monster fan on it.

I'd agree, but when you're in the range of a $40 GPU sometimes it's not worth the added investment to buy a large replacement cooler. The OP obviously wants to fix his sister's GPU without a cash outlay. Thread crapping and implying his sister is ugly doesn't really help answer the guy's question.

Hm that's a nice idea. If my half-assed attempt with velcro fails I could give this a go after Newyears. I'll post my results too (for science!).



I thought BD231's joke was mildly amusing, wasn't insulted at all and my sister wouldn't be either.

When you're cheap you're cheap, I'll leave that to you MrTeal.

My vote is to slap a 120mm or even an 80mm on the cooler. I did this to an old FX5600 and worked wonders. Make sure you remove that plastic shroud. (Or at least try)

I like the idea of using an old PCI bracket to construct a holder for a larger fan. Personally, I borrowed a 4 1/2" hole saw to cut two holes in the side of my case (one over the CPU and one over the GPU) and then used a filter / mount like this to secure them.

The PCI idea is less radical but recirculates warm air. It has the benefitS of not needing a 4 1/2" hole saw (they run over $50) and directing the air right onto the heatsink. My configuration blows cool air onto the fan area, but from the side, not directly. Lots of good ideas and information in this thread.

Please again consider that there are people in this world who do not wish to spend at least $40 to repair a card that is worth approximately $40. It has nothing to do with being 'cheap', but instead is an issue of common sense.

Zip tying a fan in place has been a very cost-effective solution for me on more than one occasion. I remember an old Duron system that was long in the tooth and had one of those tiny 60mm fans on the heatsink. Managed to get a couple of hundred MHz and cooler temps by replacing it with a jury-rigged quality 80mm fan.

Yeah ok McGuyver, yall sure do reference price a lot for not being cheap ; and it's 20 bucks not forty quit lyin. If you feel zip ties on your hardware is appropriate go for it. I'm not wasting that kind of time when there are better options out there on hardware that's obviously worth more than $40 dollars to said individual. Just because its old doesn't mean it's garbage, and personally I think zip ties or the like are garbage options.

To each their own.
