All PC fans ramp up when playing games

[DJB-711]

I have legitimately tried everything to get my PC fans to stop ramping up when playing games, and that does also include my GPU fans too, along with my case fans, they too will ramp up to 100. Despite me setting a fan curve on the GPU (RTX 3070) it still also ramps up too along with the case fans 

 

Here's a list of things I have done 

 

- Made a less aggressive fan curve for the case fans in BIOS (it still sped up on its own at random points during gaming) 

 

- completely flattened the case fans curve in BIOS in order to see if it was going to ramp up still (it still did) 

 

- Downloaded Fan Control (this actually worked for a bit but whenever the same circumstances for the ramp ups were replicated it once again ignored the curve on Fan Control and blasted at 100% 

 

- changed the input temperature in BIOS from CPU to System to see if that did anything while also changing the fan curve to a normal one (once again it was ignored) 

 

Is there anything else that could be causing these ramp ups as the fans get really really loud whenever I'm playing a game? Whenever I pause the game and resume it ramps up to a 100, whenever I change a setting in game it ramps up to a 100 and loading while in game also makes it ramp up horrendously.

Is this a pre-built? I haven't heard of a system's BIOS overriding Fan Control before.

 

With Fan Control, did you try setting a Time Average for your temperature, rather than using the raw temperature data? This can help to smooth things out if you have components with spiky temperature behavior.

 

Also, what temperatures are you actually seeing when this ramp up happens? Are the components actually getting hot?

temps?

I personally doubt what im going to say myself as they dont run 100% all of the time, but do you have DC fans running on PWM settings?

Welcome to the forums!
Strong first steps to troubleshooting. 
Can we get a full list of specs? 
Also, is this only in games? Or if you spin up Prime95 and furmark does it do this as well?
We really need to see some temps at idle and under load. Fans ramping up usually means there's a thermal problem.

Apologies for my rather vague explanation of the problem in my original post, it was 1AM where I am and I had already spent a couple of hours trying to fix this issue, so I was more than a bit tired and frustrated when I wrote originally. 

• Motherboard: Gigabyte B450 Gaming (not DS3H)

• CPU: AMD Ryzen 5 5600X

• GPU: NVIDIA GeForce RTX 3070

• RAM: G.Skill Flare X Series Red 16GB (2x8GB) DDR4 2400MHz CL15

• Storage: Samsung 860 EVO SATA SSD (model: MZ-N6E)

• PSU: Antec VP700 Plus 700w

• PC Case: Antec GX330

• Case Fans:

  • 2 original case fans (1 intake, 1 exhaust)

  • 3 Corsair fans (daisy-chained to SYS_FAN1 header)

• CPU Cooler: AMD Wraith Stealth Socket AM4

Operating System: Windows 10

The Problem 
My fans keep flaring up when doing any kind of loading in game, whether it's actually loading into the game, loading parts of the map, or even just pausing the game for 10 seconds and resuming the game. All these things cause my case fans to ramp up to 100% for some reason. I have tracked both the CPU temps and the GPU temps to try and pinpoint the issue. When playing RDR2 the highest temp reached by the GPU was 75 at the most and the CPU reached 70 (both in Celsius)  

I have tried using FanControl to make a custom fan curve for the case fans so they don't ramp up like that. It does work but when I put it under the same conditions that cause it to ramp up, it ignores the fan curve entirely and ramps up anyway. I then went to the BIOS (I uninstalled FanConrol to make sure they didn't interfere with each other) and made a fan curve there, one that I got of YT that was meant to have the case fans spinning at 60% at 70 degrees (CPU temp). Still got overridden and ramped up when in game. I even changed the temp input sensor in the BIOS to detect the motherboard temps instead of the CPU and it still flared up, I tried changing the fan interval in BIOS and it still did nothing. It seems that something is overriding whatever fix I try and I am having a hard time pinpointing exactly what the issue is 

I am currently at a loss at what to do because no matter what I do it seems to ramp up in the same areas no matter what I try. 
Feel free to ask questions or give advice or suggestions, I am more than willing to try them and resolve this issue

This only happens in game, I haven't tried either of those 2, but I will give them a shot and let you know the results 

 

CPU temps when idling is about 40-50 and when gaming it'd be 65-70 at the very most (Celsius)  

 

I just made another response going into detail about the issue so if you want the whole story you can read that as well if you like

What are you using to measure that?

OpenHardwareMonitor, if you have another suggestion for measuring temps I am more than happy to check it out

It's probably not the cause, but you should be aware that PSU is E Tier - Avoid

That's very weird. I would check for a BIOS update, and if that doesn't fix it, probably try reinstall of windows

No, I mean what do you use to measure fan speeds?

 

But also something like hwinfo64 or MSI Afterburner overlay would be more trustworthy for accurate results IMHO.

Alrighty people I have some updates 

 

So turns out I was wrong from the beginning, it is my gpu fan that ramps up, not my case fans, I just assumed case fans because of the sheer volume that was coming from my GPU fans 

 

I am going to link a video that I filmed regarding the issues on my PC 

 

First things first, yes it is on the floor, but the only reason it is, is because I wanted to experience 1440p and only my TV was capable of that not my monitor, so don't be alarmed, it is usually on a desk 

 

Secondly, even when it is on my desk at 1080p the issues still persist at the same rate 

 

Thirdly, I have set my own fan curve for the GPU but it keeps getting overrun by something else as you will see in the video below which will be linked as a Google drive link. 

 

Please ask any further questions if you have any

ATTENTION FUTURE VIEWERS OF THE THREAD THAT HAVE THE SAME ISSUE, I SOLVED IT

 

The solution was quite simple, when I got the GPU I noticed that due to it's length, it was going to sag if I left it as is, so it compensate I used an object to support it. 

 

Well it turns out upon further experimentation, I saw in proper sunlight, that the GPU was now actually angled too far upwards, thus now when adjusting it to be properly level, all issues are resolved, the fans are normal and obeying the curve, and predomance is actually a lot better, a ton better, temps have gone up slightly (5 degrees) , but I assume that's only fair seeing the big performance boost gained. 

 

Thank you all in this thread who helped me and I hope anyone who has this issue in the future sees my post here.
