Has anyone ever re-pasted or replaced an X570 PCH fan?

[goldfritter]

My current CUD-based obsession is trying to make my PC quieter. At this point the loudest thing at idle (other than a mech HDD) is the PCH fan on my X570 TUF mobo. It's not very loud but it makes quite an annoying whining noise.

Info on Google is scanty. I have tried setting a fan curve using FanControl (great software btw) but it isn't really satisfactory. If I set it too low, the chipset heats up alarmingly quickly.

Has anyone ever tried opening one of these up and doing a re-paste? As far as I understand, there is a thermal pad there, but replacing it with paste can improve temps. Else I can replace with a better pad.

Or is it possible to replace the fan entirely, maybe with a 40mm Noctua? Importantly, what type of connector does the PCH fan use?

I am aware that taking the heatsink off myself would answer all of these questions for me, but that would require taking the mobo out of the case to loosen screws, and I am enormously lazy to do that.

It is still under warranty, but I doubt they'd RMA because of this. That said, does anyone know if there are any warranty void stickers in the way of taking off the heatsink?

Or am I better off just living with it until I get another mobo with a passively-cooled chipset?

Thanks for the input folks.

I think this is your board. Might answer questions.
Go to the Imgur page for descriptions on the temps.

My X570 TUF does not have that fan. Must be another revision.

That there is the X570"S" chipset. It's not always labelled as such.
There's a lot of confusion and misinformation around it as it was never really officially launched as a new chipset from AMD. It's essentially the same, but Wifi 6E support is the giveaway.
All boards running that chipset are designed with a beefier heatsink to negate the need for a fan. There's some argument that the power consumption has been reduced, too, but I haven't seen any hard proof of that.

Sell and get B550.

@Moemfie_ZA @KURT_COBAIN sorry guys I hit my head and was sensible for a moment.

I'm back to myself now. OP, please evaluate your priorities in life, you clearly need to upgrade to a better platform due to this pesky little fan.

You need, nay, deserve a ROG CROSSHAIR X670E EXTREME with a 7950X.

Thanks, this helps a ton.

The board is still under warranty so I think I will lay off the mods for now, and probably just suck it up until I go Zen4 3D or 13th gen or whatever.

Create a 120mm fan to chipset adapter and 3D print it.

Or just make sure that there’s good enough airflow over the chipset to keep the fan from spooling up too high.

So this took a weird turn.

On a whim, I sent a video of the fan noise to Wootware from whom I'd bought the board, asking if they thought it was faulty and if I could maybe order a replacement fan from the supplier to switch it out myself. They said it sounded off to them and they'd check with the supplier.

After a week of not hearing back from the supplier, I asked if I could just take the board straight to the supplier; Woot said yes and confirmed it was still under warranty at Pinnacle.

Dropped it off at Pinnacle on Monday. Today I get an email from them asking for the invoice from Woot. I send it to them and they reply "thanks, but we don't have replacement stock, we'll refund it."

An hour later I have the full purchase price of the board credited to my Woot account (and an email confirming I can cash it out as an EFT if I want).

Now I don't know what to do. I already switched the rest of my main build to another system. I was hoping to use the returned/repaired board to put together a spare PC for someone using leftover parts... Now I either have to buy a cheapo board for the spare PC, or I must upgrade to AM5/Raptor Lake and pass down the current build. With Zen 4 3D just around the corner

Not that I am complaining. If I sold the board used now, I'd get a lot less than I paid for it back in 2020.

Anyway, moral of the story I guess, if you think something is a bit dodgy with one of your PC parts, check with the retailer/supplier/manufacturer if there is some way they can help you sort it out. Things might turn out differently to what you expected.

Sell your left over parts and stash the cash for the a new build when zen4 3d drops.

Yeah this is a good plan, although I did offer to lend the leftover components to someone for a build. And now there's no mobo for that build anymore, I thought I'd at the very least get the board back with the faulty fan. Which means it'd either have to wait until I upgrade (and I'm not even sure I definitely will go Zen 4 3D, I might wait even longer), or between us we'd need to buy a used mobo to use in the interim.

I guess there's no rush though. At least Woot isn't like some places where your store credit expires and you can't cash it out...
