MSI RTX 4070 Ti Super Fan replacement.

[dfonda]

So unfortunately I have 2 of these and one has failed fans and the other has one of the two on it failing.

It should be a warranty replacement. (3 Year on these and they are not a year old) Or...These are the OEM replacements. What I wish I could do is upgrade them to a much nicer set. I just don't know if it can be done. It looks like MSI has been using these crap fans for years. I know how to replace them as its just a few screws and a wire.

Any help/advice is appreciated. I know @WhitehawkEQ has a lot of experience with replacing (Most of us think he has too much experience )

RMA.

I would ask MSI if you can send them fans only. If they agree, you can use other fans with zip ties (set lower power limits or something, but still have usable cards for the time of replacement). I don't know if they accept a warranty if you replace fans on your own and anything happens to the cards. They are sometimes acting weird.

There is a 3D printed frame on Etsy that I am thinking of grabbing. Lets you deshroud and add 120mm fans. Not sure if I am going to do that or just mount 3x 92mm fans on myself. My Zotac has a noisy fan, been like that since day one lol..

I do have the luxury of plenty of GPU's. My concern is that the GPU should work for a few minutes even without fans. So they can just have the whole card.

I honestly thought replacing these crap fans would be a lot easier. It's involved and with 3 years warranty on a '24 GPU can't do much. I was talking to Whitehawk wondering does the GPU know if the fans are not turning or is only excess heat shutting down. I felt this GPU should have worked without the fans.

Trick it. Jump the headers.

So it does have a failsafe if the fans fail ? Or is it just triggered by heat ?

A lot of these cards have a zero fan feature, but the fans kick on at a specific temperature. I'd imagine if the GPU doesn't work at all with a borked fan (unusual), then it's a connection thing.

Every GPU works with a broken fan. You can install water blocks or other 3rd party coolers connected directly to some other power source. There are still sensors that read temps and push fans to some speed, so even if there is no fan, the card tries to use it. However, modern cards are thermal throttling. I just don't know how much, as I had no broken fan case for a long time (noisy, yes, but still spinning). I assume they just slow down to the point something crashes or you see a bluescreen, which is some kind of OS failswich.

Yeah these are pretty bad. For example if I spin it with my finger it barely makes one rotation and stops. I thought at first its just rubbing plastic housing...but no , the bearing are Kaput.

I hope my black SKU holds up for a few weeks till I get this back. At that point I'll start an RMA on this one. Man its just such a waste of resources for them and myself as I have to pay shipping. That will cost as much as the fans themselves. They don't ship parts. I'll give them credit for approving RMA in 3 hours.

Again this would be such a pain for someone who doesn't have 6 4070's sitting around.

Thanks for the info Folks.

Warranty returned. Fans spin perfectly. It's working so far F@h if it makes through 24 Hrs I'll consider it fixed. Even tho they specifically said do not send it in original box as it wouldn't be returned. I sent it anyway for the safety of the GPU and they returned it. Most be a guideline rather than a rule.

It has been running 24/7 since Tue night , all good.
