Is it okay not to have GPU or CPU fan at 100%?

[Merc]

If I set the max speed to say 80% will it still keep my pc cool enough? I would imagine it would be a case of monitoring the temperatures to see what happens? I want to find a happy medium of a quieter case but with safe cooling.

It should never even reach 80% with most coolers. Just leave it to default.

If it does get too hot the GPU/ CPU will simply downclock to cool down.

well for starters what your CPU, CPU Cooler and your GPU anyway? Speeds and temps can be controlled and monitored with Speed Fan, NZXT CAM, MSI Afterburner as example.

To be honest, I have my GPU fans attached to the Motherboard until the cable comes to attach them to the card again (I replaced the stock fans) I had them running at 100% at 60oC I put it down it a bit but not too much as the temperature is monitored from the motherboard rather than the GPU itself, as for the CPU I will lower it a little, I bought a new Noctua cooler for the CPU so I don't think it needs to run super fast.

Fans should typically run about 40-50%. But it really depends on the make and model of fan in question - Noctua Industrial fans love being revved out to high RPM, Thermal Riings very much don't.

100% means the fan is delivering absolutely every possible iota of RPM that it can. Which is something it would never do unless you specifically force it to by adjusting voltage. This will make a massive amount of noise and requires extra electrical power, but may not actually increase your cooling performance. You also risk causing excess wear on the fan bearings - normal fans aren't designed to be abused like this.

It's absolutely not necessary to run a fan this hard. Even 30% will usually keep your system cold enough, and 60% should get you through anything. But if you insist on running an extreme-rpm extreme-airflow cooling system, invest in a set of Noctua PPC Industrial fans. They're actually designed for this sort of tomfoolery, and deliver their best performance at high RPMs. They're also some of the very best cooling fans currently available.

You can run your fans at whatever speed you see fit.

The only limitation would be on DC fans, where you control the speed by voltage change. You can only go so low before the fan isn't getting enough power to operate.

PWM fans have a little more control.

Another limitation would be noise. The higher you rev a fan, the more air rush and engine noise it produces. Running every fan in the system at 100% would make quite a racket.

I just played about in Bios and lowered the max settings and the temperatures are the same in a high demanding game, thanks guys.

P.S. I think my exhaust fan makes a noise due to air blowing on the specific grill pattern to be honest.

You could easily check that. Fans are held in place with four screws. Unscrew the fan, place it on your desk and boot the PC. If it's suddenly quiet, you'll know you were right.

And before you ask "but won't my PC instantly blow up if I run it without an exhaust fan?" It won't. Computers have very good cooling and don't actually produce that much heat. Even if they do overheat, it won't damage anything - the system will self-regulate to stay cool.

Sidenote to abck this up:
you can even dismount a CPU fan or the entire CPU cooler while the PC is running without damaging anything :D.

I very much appreciate your input :) I can't be bothered to mess about with the fan now but when the cable comes so I can attach my new fans attached to the GPU to the GPU itself I will take the exhaust fan out and install it on the outside of the case and attach it to where the GPU fans are plugged in now, the cheaper exhaust fan I had before made the same noise and I assumed it was the fan but I am pretty sure it is due to the honeycomb grill that the air is being blown at, if that fails I may just not have an exhaust fan as my CPU cooler has a 120MM fan blowing air directly at the back of the case (but I am 99.9% sure it's jsut the wind on the grill and that putting the fan on the outside will hopefully fix it :)).

I am just trying to make my PC as quiet as possible but it's proving a pain in the butt ha.

uhm what I lsot you sorry. GPU fans. those are not standard fans and you should not connect case fans to the GPU but to the motherboard or a fan controller. Also case fans should be AF (Air flow) while fans that needs to push air through a heatspreader/radiator should be SP (Static Pressure).

[Merc]

Case fans are fine on a GPU in my case at least, (I am waiting for the cable to attach them to the GPU again). I say this as I have seen the results from somebody else who used the same fans on the same GPU and the card is kept cooler at a quieter noise level.

I wouldn't consider noise a limiting factor, as it doesn't limit it from operating at top speed. Rather call it a comfort factor.

I run most of my fans at top speed without making a racket. Depends on the fans you're using, of course.

[Merc]

Everything is fine now, it's just the exhaust fan which I'll re-position to the outside of the case, I can hear it now, I put my hand across the back of the grill tight and the noise stopped so I know for sure it's the grill.

First off, Case Fans don't plug into GPUs. Like who does that?
Yes it is a rather rare feature on some GPUs, but it is not a common feature.
If your GPU does not offer a header for this, never try to run extra fans off of your GPU.

Just plug into Motherboard; folks do realize that for every Fan Header on the Motherboard you can run 2-3 fans off this, yes? Or if the fan will just be ran at full speed anyways, run it off the PSU directly then, which is fine.

Positisioning Fans to outside of your Case? Say what now...

As for the backplate it's probably just a slight rattle. If you have other loose slot covers, just remove all of them, you don't need them.
