Motherboard fan question.

[Zarginnia]

Hi, i have a MSI MAG X570 TOMAHAWK WIFI and i accidentally damaged the fan on the motherboard so 4 fins less on that one. Can say that i have ever seen it spin.

So my question is: Do i really need it? If so how hard is it to replace?

I have pretty ok airflow in the system but that might still not be enough.

would it work to just take w/e heatsink there is from another motherboard? like an older one or any at all. Remove fan and heatsink then attatch the one from another board?

most other chipset are around 5-8w, not 15w
and chipset coolers dont use a common mount like cpu sockets
universal or thermal epoxy is the only way to make sure its contacting and cooling properly

Take the dimensions of the fan and buy a replacement off Amazon or Ebay.

There might even be a product code to find the exact fan on the fan.

i said that in the first reply
but the oem fan is probably custom, size may be common 40-45-50mm, but not standard mounting holes, or even its power connector may be different

with a universal aftermarket chipset cooler, it will fit, and you can plug it into a cha_fan header and set it to sb temp if bios has the option, or keep it at 50-80% (using dc voltage) so its always spinning

keep an eye on sb/chipset temps with hwmonitor to make sure its staying cool

Ahh missed that bro, just had a look at the MB, kind of awkward looks like it's part of the actual heat sink, yeah good old fashioned sticky sink and fan.

You could always just email MSI or on their social media and see if they will send a replacement, this sometimes works.

quick fix just zip tie any old cpu fan you have laying around (I have several 60mm amd ones) until you can get it replaced and yes fan is needed!

I have the same motherboard as the thread starter except it's the "X570S" version. The chipset has no fan by default. Looking it up, the only difference between the X570 and X570S is precisely this. Somehow, the X570 uses ~15W and the X570S uses ~7W. That's around half as much, so what's the difference then?

I've noticed my chipset heatsink gets quite hot to the touch (reminds me of my old X38) but its temperature is often way below its rated maximum.

I would not suggest the thread starter to run it without a fan if it had one by default. That being said, I recall that the X570 usually only "needed" it and spun it up when it was under heavy load, and this often meant a PCI Express 4.0 (or maybe fast 3.0) drive in the secondary M2 slot being hit hard. Most gamers don't actually fully utilize (peak bandwidth-wise) storage drives, let alone multiple at a time, which is why you often hear them saying they never notice that fan spin. So the X570 seems to be on the edge of needing a fan and that 15W rating is probably a worst case scenario that few push it towards. I'd still replace it mind you (because if it can go that high, you want the safety net), but that might be the answer of why you noticed it barely spin.

it should be possible to replace it but, you need to buy a new one from msi. it seems to still be sold however so, it should not be a serious problem.

found this one

that might work? its the same number and looks like it and has the same screw holes aswell.

So it is needed, but also not.

First, if the fan has even blade numbers, carefully snap off the opposing blade. If you balance the fan it will still work. It wont work as well, but for what it is doing it just needs to work at all and it will be good enough.

Second, check in your BIOS, many x570 boards support a "silent" profile for their chipset cooling that *is designed to keep the fan from running*. Yes, this does mean that technically, in situations where the chipset gets very hot, it will thermal throttle and run a bit slower. But in 9/10 cases the IRL impact will be zero to minimal, and if choosing between not having a working fan and thermal limiting vs breaking things, this is a simple option that wont make a difference in most performance cases.

Unless you are running a super high end GPU *and* hammering multiple Gen 4 drives at the same time there will be little use case where the chipset gets hot enough in the first place.

Yours is just an x570 running in silent mode with no options to remove the TDP limitation. So its got x570 features, but if it were ever pushed fully it would not put up full x570 performance. This is different from B550 which lacked features that x570 had. So you are getting the "best of both worlds" with the trade off that in actual high demand sitruations your x570 will keep doing all the same things as any other x570, just not as fast.

I sort of suspected that because having half the peak power consumption is a big difference.

I did notice the SSD connected to the secondary M2 port returned slightly lower peak bandwidth numbers than the one connected to the primary M2 port, but it wasn't by a lot.

I'm not sure if this specific to the X570S variant though since I read that AMD used a PCI Express 4.0 x4 connection between the CPU and X570 chipset. A PCI Express 4.0 drive alone would be able to use all that, and since the chipset controls other things like USB controllers and such, this means a PCI Express 4.0 drive in the secondary M2 slot won't always reach peak numbers.

But other than that, which seems to apply to the non-S variant as well anyway, I'm not sure what the tradeoff is. Maybe it limits the peak bandwidth numbers a bit lower on top of that for the S variant. In either case, I wanted less noise and failure potential so the S version attracted me.

if it looks like it will work, and has similar plug, give it a shot
it has 4 pin connector so its pwm, make sure the board has the same kind of plug
