Twin Frozr II fan horrible noise - Page 3

Glad I'm not the one bumping the year old thread, but the back fan on my MSI 560ti GTX is sounding like a hard drive actuator when its up to speed. Has anyone RMA'd one of these with MSI? I wish they would send me a new fan assembly or cooler, but I know that wont happen. I don't have a backup card right now..

The card is about 8 months old so I'm not going to void the warranty trying to oil it.

Has anyone found a source for these fans?

I've heard a lot of reports of ****ed up twin frozr ii fans. Its an awesome heatsink, but rare fans that perform strongly and quietly but break down with a short lifespan and impossible to replace, for the cost of the dual fan module you can find a twin frozr ii heatsink on ebay! Also, msi does some sleeve work on the fans, so you can't find the exact fans, msi gets 2 power logics and splices the wires, ties them up to the same header, and sleeves them (that's why you don't see a y splitter like you do with a dual fan module of the same fans, you'll notice the 2nd fan also just has 3 wires instead of 4, whereas dual fan module is 2 x 4 wire fans with a y splitter).

Unfortunately, 75x75x10mm dual or 2 x fans w/y splitter, frameless with 35mm by 35mm by 35mm triangle mount is just about, if not actually, IMPOSSIBLE to find as PWM.

Great fans for performance, gaming, general usage, but if you like 24/7 server workload crazy gpu **** like folding (folding is gpu intensive right ? You get the point...) they will die out and get noisy as their lifespan shortens. Brand new, they outperform any aftermarket heatsinks stock fans though.

Replace the fans with like 120mm cabletied fans instead, google dahlsys twin frozr ii on how to do it. I'm in the process of trying to replace the fan blades / fan head (I broke 2 blades on accident) from a donated twin forzr ii fan module with broken motors that was donated to me by the guy from dahlsys.

And its true, its possible to remove the fan blades, but SOMETHING is glued to something that makes it inpossible to pry off without mangling something. I got the head off, but I gotta try to find a way to take it off without manginlg the motor set up...

my replacement (new) 6950 fans sound a little weird from the word go. Odd harmonic vibrations at the exact speed they like to run at while gaming on the stock fan profile. I'm avoiding these heatsinks in future, unless for the TFIII they stepped up to normal spec'd replaceable fans... will cross that bridge when I come to it.

You know fan damage isn't covered under msi warranty because it counts as physical damage. Really bothers me since they said "oh just RMA it" and only told me when it got there that I'd have to pay $55, so I told them to just ship it back.

msi only fixes messed up gpu (i had a 460 that had to be underclocked to ~400core/1400memory from 751/1800 stock in order to not artifact) and maybe blown out stuff on the GPU. They do cover overclocking up to what you can do in msi afterburner though, including overvoltage.

I believe the tf3 has slighyl different fans - like it's the same power logic and model number and everything, but the fan blades obviously look different. Maybe it's just the same model with different fan blade, because i know their dual modules and some like with MSi logo on it go by same serial number too.

power logic, model PLD08010S12HH DC brushless fan pwm 4 pin sleeve bearing

I'm going to either glue back my fan blades, or replace the fans (even with an ugly y splitter/no sleeve, or maybe find another pwm 75mm fans, maybe i can switch out the fan blades), or just buy a twin frozr ii heatsink on ebay for $34, depending what's most cost effective (ie okay with higher priced twin frozr if i can sell mine with 1 broken fan for like $10-20).

actually, you know what. **** it, im just going to break apart the back of the fan. Glue exists, so I'll remove the fan head, probably break the back plate, just avoid breaking the mosfet chip on it this time around, and then glue it all back together.

bahahaha.

I got the 2nd one off! I figured it out!

Okay, what you have to do, is stick like a really thin... knife, razor blade, tweezers, between the PCB, blastic non-frame thing. It's glued onto the PCB, so what you are trying to do, is break the glue, without breaking the black plastic.

If you just stick the knife in there and pull, you'll break it. You have to find out where the gluespot is

Screwed up


Not screwed up


You can see that the glue is in different spots on each one, too. The first one, glue was in top right and middle right, the 2nd one, it's in the top left and middle left. i think

So you gotta sort of stick the knife all around, and just pry up just a tiny bit, to break that glue. You go all the way around. Make sure you DONT pry up at the 'top', where the voltage regulator chip is. If you stick a knife between it and the plastic, it'll break off, as you can see in the first pic. So stay away from it, there's a huge hole in the plastic frame for it so the glue won't be there anyways. It might be next to it though, in which case be careful not to break the 'legs'.

Once you've broken the glue, stick 2 knives/blades/tweezers, on opposite sides, on the middle-left and middle-right. If you broke the glue, it should come be easy to sort of wiggle up, just sloooowly apple pressure to pull it up. If when you push up the thing resists, then you haven't broken the glue.

If you broke the glue, it'll slowly come out, and your good!

Then, it's as simple as removing the fan blades/head as any fan - pull the c-ring clamping the fan head in place (there's 2 of them, actually, the bottom one is a *****, just wiggle the fan head off as you lift a side of it up since there's no way with tweezers your gonna straight pull it out, its in deep).

The frame sits in so tight, I'm not sure why it's even glued in at all. I don't think you should even bother re-glueing it afterwards.

edit: Thinking back on it, I think due to how torque works and all, I think it's best to use a thin knife or razor blade to slightly pull up to break the glue, and then use tweezers to pull it up, just on 1 side. A knife blade applies pressure upwards on the entire plastic non-frame, which might break it, but tweezers will pull up right next to the middle 'base' thing and will lift it up really easily. Quite frankly I don't know if you even have to use a knife to break the glue, a single set of tweezers pull up the thing so easily.

If I'm you though (or I'm me when my gtx 460 gets back and I have to do this to real fans), I'd recommend you just try with tweezers lightly to pull it all up, and if it is resisitng, work a knife/blade around to break the glue (and be careful around the voltage chip and make sure not to break it, as it WILL break if you put any pressure on it or the legs of it).

I'm still waiting for my gtx 460 to get back from msi (bastards told me 'yea just send it in no problem that you broke it on purpose! we got you covered, dont worry about trying to buy the fan from us!" and then when it arrived, they told me hey bro its $55 and we dont have replacement fans), but once it does I'll be able to do this.

I'm a ******* internet hero man. I've seen SO many people say "qq my gtx 460 fan blades broke on accident, how do i replace the fans there's no replacement anywhere, omg msi wants $55 or i live in britain and it'd cost $150 just to ship it"

Anyways, I was lucky enough that someone nice sent me a twin frozr ii fan module that had intact blades but broken motors laying around still, so that I could both test this on, and use the fan heads as replacements. If you broke the blades of your twin frozr ii fan, just buy a single Power Logic PLD08010S12HH for ~$9, pop off the fan head (pop it off this one first, in case you **** up), and then swap it on the twin frozr dual fan module.

Edit: The fan blade / head makes contact with the metal thing in the plastic frame. So if you have a twin frozr ii fan that's making noise, it just needs some grease. Put grease in that hole, and your good to go.

In most sleeve bearing fans, when you open up the back sticker, there's a rubber cap to open. In these fans, it's hard plastic instead. So you gotta dismantle the fan to relube it, whereas most fans you can open it up from behind.

Great research, but honestly if the fan is crappy, all the oil in the middle east wont keep it running for long. I'm just annoyed MSI doesn't offer a fan replacement, there are several threads going around about them.

I've always disliked sending in a card with 1 problem to get a refurbished card with others.
