View Full Version : G74SX Fan Always On

12-07-2012, 01:09 PM
I just bought a G74SX from a local computer store. It was pretty well never used, as it was in a warehouse all it's life. My question is: does the fan always run? i just booted it up and right away the fan started at full tilt. It is not dusty as it is brand new.

Load up HWINFO64 and choose to enable the EC Sensor on the first launch. It will display CPU and GPU Fan Speeds. The G74SX fans run at ~2180 RPM at idle.

Where do I fond the HWINF064? I did a fresh windows install so it might not be there.

Type HWINFO64 in a Browser Search box and download it.

You have HWINFO64 installed - that's good! Now you need to enable the "ASUS G73 EC" Sensor (the one with the "X" in the red circle in your screenshot). It will report the CPU and GPU Fan Speeds in RPM. The "GPU Fan" Sensor under the GPU Memory Clocks ALWAYS reports "100%" regardless of what the GPU Fan Speed is at the time.

my GPU and CPU speeds are around 2100 RPM

my processor is a 2ghz one but this thing is saying they are running at 2.5. could they be overclocked right now?

The fn is still going, the laptop has been reset and is on power saver mode too.

I am triple posting because I don't want to burn my fan out.

The G74SX fans always run at ~2200 RPM when at idle. So your fans are operating normally. Don't worry, be happy... Go game in peace and triple post no more!!

is there a way to turn it off or slow it down for when i am not gaming, idont want to reduce the life of it and it's a bit noisy.

The fans in my G74SX are not noticeable when running at 2600 RPM during normal work. If I listen for them in a silent room, they can be heard, but most of the time I don't notice any fan noise.

A bad bearing or fan blade contacting the housing or a piece of plastic debris in the laptop may result in excessive fan noise. A video where you hold the video recorder at normal head level from the laptop and speak in a normal voice volume will help us determine the extent of your fan noise issue.

As I posted earlier, your fan speed is normal. The G74SX fans always run. The lowest speed you are likely to encounter is ~2150 RPM. To my knowledge, there is no way for a user to adjust fan speed. They are controlled by the thermal profile in the BIOS.

Fan Speed is auto detect by system, don't worry it.

My fans read at 2600rpm but it is summer here and quite hot, so I don't think it is a problem? The noise certainly doesn't worry me, heck I used to run a GTX285 in my old desktop, when you played a game the GPU fan would go into turbo mode and I swear you would think someone put a dustbuster in your PC Box, damn it was loud! By comparison this is no noise at all! Although I do notice the difference now it is summer, the fan is definately spinning faster than Winter
