Fan silencing a 32GQ950-B

I now want a 32 inch Oled 4k display but I am waiting for them to find away to raise the brightness.
They also need to be standard RGB stripe (unless Windows changes it's ways). A couple do already exist (LG 32EP950 and Asus PA32DC) but they are 60Hz only, aimed at professionals, and £££. Currently, the problem with increasing the brightness or refresh rate is how fragile the organic pixels are at this size.

There was another model I looked at after I saw the 32EP950. It was a Dell and it was more pricier. For a split second I was tempted to pull the trigger on it. Which to me a split second of temptation is an eternity.
 
Purchased a LG 32GQ950-B monitor that does so many things right, but there's a fan built-in that gives a constant high-pitched and warbling whine that's just incredibly annoying to be around. Anyone have suggestions for how to silence this if mods are on the table?

I can disable the inbuilt fan from spinning and verified there's no coil whine, but without the fan running the display shuts itself off after about 30 seconds. Best guess is that it's checking whether the fan is spinning and not the internal temperature, which should be low the way it's being used. That makes it difficult to work around and I'd appreciate any suggestions others might have.

Like I said the combination of size/resolution/ATW is awesome, but I'll have to return it if I can't get it to be quiet. If there's something on the horizon with similarly good viewing angles I'm up for waiting a few more months.
I have exact same problem with my new 32UQ750-w. I thought it was connected to some power circuit component. Are you sure it’s the fan? My sound sounds like high pitch whine from my sitting position and when I put my ear close to the air holes on top of monitor then it sounds more like some lower pitched buzzing+high pitch frequency. It is not loud but it’s very irritating how it resonates in a quiet room. There is no option for fan speed in my service menu. Even with ‘aging’ turned ON.
 
In the case of 32GQ950-B it is definitely the fan. Changing the fan speed in the service menu changes the tone or eliminates it. It is a very high frequency noise, quite similar to coil whine.
I see. I wasn’t sure if my model has fan but then i messed with some settings in service menu and the window popped up with some info where among others it said FAN:OK
I would rather buy some LG with 60 hertz if it doesn’t have a fan just to have a quiet monitor. So disappointed with this cause the panel is perfect and i love everything else about it. Also I returned the first one and bought the same model which is exactly the same. (Same sound)
I wouldn’t be bothered with the normal humming of fan but the high frequency is just…i can’t ignore it. It’s a constant frequency. It doesn’t change pitch wise. Even if i turn of my pc I can still hear it for a few minutes until the monitor automatically cuts the power. Goes into kinda deep sleep mode i guess.

Hi everyone,
I recently purchased an LG 32GS95UE-B monitor on September 28, 2024. Unfortunately, I've encountered a frustrating issue: a high-pitched rattling noise coming from the back of the monitor. I'm using it at home, I live alone, environment is quite.
I've tried several troubleshooting steps, including resetting the monitor settings, unplugging it for 15 minutes, and playing HDR content to warm it up. Unfortunately, none of these solutions have resolved the problem.
With only a few days left before the 30-day warranty expires, I'm seeking advice on what to do next. Has anyone else experienced this issue with this particular monitor? Any suggestions would be greatly appreciated.

just a thought on most mobos if you unplug the cpu fan header you get a warning during boot, but simply plugging in a 4 pin extension cable (unconnected to a fan) is enough to bypass the warning automatically, just wondering if the same would work here whereby if the monitor is shutting down due to lack of cable connected, a simple extension being plugged in may trick the monitor.

Thanks for reply folks.

That might work, but I'm concerned about the display overheating. I'm still under warranty, though.

Return it for refund and don't buy a model with a fan in it as this is what can happen. You're lucky it's still in warranty.
Thanks for the advice. A refund would be ideal, but I'm worried about getting rejected by warranty services. In Kazakhstan, it can be tough to get RMAs approved, and the seller/service center often claim the noise is normal.
I was really excited about this LG OLED monitor, especially since I almost ordered it from the US. I'll definitely try my luck with the warranty claim, though.

that would be my worry also, if its a standard 4/3 pin fan, and there's space, you could try to replace it with a bigger model, say the smallest noctua for instance that you can find and it should bring the noise down; or you could even use a 7v or 5v inline regulator(not 100% sure of the name) extension to drop the speed of the current fan, usually most aftermarket cpu coolers come with these.

Someone posted a picture of the LG monitor's cooling fan on Reddit. Do you think it's a standard PC fan, like the ones that connect to the PWM header?

looks to be same/similar format as a laptop fan, it does have 4 pin based on the cables, but its hard to say what the connector will be as we cant see it, but i highly doubt its a standard 4 pin pc header i reckon itl be a laptop 4 pin connector of some type

EDIT: found a better pic of it here and it does look like a laptop 4 pin connector

if you've got soldering skills and wanted to do as i suggested if another fan fit, you could buy a cheapo laptop cooler on ebay with the same connector, chop of the end, grab a replacment fan, chop the end off, grab a 5v/7v resistor too if you want, chop of the ends, solder it all together and then replace the stock fan, keeping the original fan untouched for putting back should you ever want to, however i would suggest that doing so will likely void the warranty, as lg will likely claim you've tampered with it should you ever tell them you've done that and or that the fan you've replaced it with is untested with the screen.

It is certainly normally for the fans in LG monitors to make some high-frequency noise. But there shouldn't be any rattling. It is often possible to change the fan speed in the service menu which alters the tone of this noise. Sadly. this speed setting isn't retained after a power cycle.

Most LG monitors monitor the PWM fan speed. You would need a "12v fan simulator" device to replace this and prevent the monitor shutting down.

That is similar, but not the fan LG normally fits in their monitors. The one typically used is the Sunon EF60151S3-1C020-S99 (LG part EAL61800805) which has a custom connector that I could not find anywhere.
