W860CU fan speed

Is there a way to lower the fan speed on my W860CU or just keep it on low, my idle temps on my i7-620m are 37C-40C and the fan keeps going from low to medium for awhile then turns off for 1 minute then starts back up again once my temp hits 50. I tried pressing the M keep for silent fan but that's louder than the medium fan speed.

I noticed the 5870m idle fan speed is quieter than the CPU fan speed and that temp is higher idle. Anyone else experience the same?

 

you probably should remove the cpu fan cover.
it is a very common problem you can check other post about that

 

Yeah i already removed that, Im thinking it may be a BIOS issue i heard when Clevo first released this product the fan was too loud. Anyone know how to flash the BIOS with a cd?

 

What Bios version are you on at the moment?

 

Judging by your recent CPU type in there you might already have the latest bios version. If not, download the lastest bios on the sager website and burn that iso file onto a disc.

 

under power management set system cooling policy to passive rather than active

the M button take a while to work so the sooner you press it the better it becomes

look at these tweaks to decrease your temps

especially the performance decrease policy set to ideal
again under power management after some registry tweaks

the latest bios doesn't change the problem but these tweaks yes
except the fact that the bios let you disable HT which can help a little bit

disable eist with throttlestop

 

Finally it worked i turned off HT and changed the power management setting to passive and everything is normal.

The fan still goes from low to medium (mediumlow?)

I tried those tweaks, my fan goes from low to medium(medium low?), my max temp on idle is 40C, not sure what the temp is when the speeds goes up

 

Well i fixed that problem CPU problem, now i have another lol.

I put my ear next to the GPU fan and it sounds like the fan ramps up for a little bit then goes back down.

 

Fixed the problem using the downclock 5870m automatically idle temps are 40C-41C and i don't hear that fan ramping noise anymore. I really wish Sager or ATI would of used the powerplay feature, i missed that when i had my Sager NP8662 with a 260m

 

You can still undervolt it for better temps at idle and load.

 

Yeah i was looking into that, i don't know a lot about it an don't want to brick my card. doing it way isn't too bad i just need to press my hotkey and it will downclock. As for load my temps never reach 80C when using Furmark so i'm not worried about that.

 

If you use your own vBIOS, the chances of bricking your card are less than 1%. And even if something did go wrong, you can blind flash it back to stock.

 

hmm so i opened up Hwinfo32 and my CPU Clock is at a constant 3.2GHz, not sure why since firefox doesn't need 3.22GHz to run.

I opened up throttle stop and turned off Turbo boost this lowered my temps until the CPU fan went on low (can hardly hear it), my CPU temp then slowly goes back up to 50C that's when the CPU fan ramps up. I was hoping that that CPU would stay below 50C on idle.

Anyone know why my i7-620m is at a constant 3.2GHz?

 

Because that's how turbo boost works: It runs at the most turbo it can, as long as it can. I think a lot more people would be complaining if it only kicked in under heavy load. Firefox doesn't need 3.2, but it's going to do whatever it's doing faster at that speed.

What you have is a 3.2 dual processor that clocks itself down once and awhile to save on heat and power, not the other way around.

 

Alright thanks, i always thought that the processor would be at 2.66GHz until it needs more power like if a game required 3.0GHz then it would clock itself up until it meets that requirement.

 

Huh when i turn on balanced power plan Hwinfo32 shows my clocks at 1199MHz, my temps drop until the fan sounds like it is off which is nice but then my temps start to creep up takes about 1-2 minutes until is reaches 49C-50C that's when the fan comes on and stays on until the temps decrease again, i really wish my temps would stay below 50C when idle so i don't have to hear the fan constantly going on and off. the noise of the fan is equal to the noise of the "silent mode M button".

 

The mobile i7 620M should not be doing that. Turbo Boost runs at the clock levels it deems necessary. Browsing with Firefox should not be anywhere near as high as 3.2 Ghz period.

 

That is correct and during FireFox usage, it should be even lower than 2.66 Ghz. Why would Firefox demand the same CPU usage as a PS2 emulated game?

When I had that same CPU, even during Firefox browsing it was nowhere near reaching that high Turbo Boost level that you mentioned and it should not be.

That CPU can idle around 30-40C depending on ambient and considering that my more power sapping i7 820QM does not even reach 50C during light work, you should check what is going on. The first thing you will want to do is to monitor your CPU usage while your laptop is idle and identify any processes that may be using resources.

If your idle CPU usage is too high, there is your problem. If that seems ok then you should make sure your thermal paste is applied correctly.

 

Depends on the website and background software, all it takes is passing 25% load from what I've seen.

 

My CPU usage jumps all over the place from 2%-50%, I don't know why my CPU fan does this i re-applied IC Diamond about 5 times now doesn't change a thing. I have to turn my TV on just to cancel out the noise of the fan going on and off from high to low.

The CPU fan sound idle is louder than the 5870M fan noise on idle (5870M idle is at 40C)

 

About to switch to quad-core anyway, hopefully the cpu will stay at 45C or 50C, this constant fan turning on and off is starting to really annoy me.

 

sorry I went away for a while

you just have to go under power management and set minimum performance state to a lower value
This value should be 100% at default settings so your cpu is at max performance state all the time

processor performance decrease policy an hidden feature in power management seems to limit the change of fan speed when set to ideal rather than single

I have the same cpu than you and when I press the M button the fan speed just stop constantly changing
Mine stays at 1.7Ghz when I push the M button and will change to an upper threshold if the cpu isn't able to do what it is asked at that frequency
you must have some background program running which require power from the cpu

I prefer to use those gadgets to monitor the cpu clock

Yea that M button isn't very silent, kinda loud.

I have the value set at 5% and i changed the procesor performance decrease policy on single, i'll see how that goes.

 

I've just tried something
When overheating my room to 30C and pressing the M button I noticed that the cpu fan was perfectly steady like it should be but that then the gpu fan started to do the same thing probably because the room was too hot. By underclocking the gpu to 500/700 I've noticed that the constantly changing gpu fan just stopped its noise like if I had pressed the M button not for the cpu but for the gpu
So maybe if your place is quite hot
underclocking your gpu will help a lot to reduce that noise because both fan seems to make that noise (it obvious but it should be said)
I'm using the AMD Gpu tool to underclock the gpu

 

sorry double post

 

Yeah i have already underclocked my GPU to 200/300 and the fan is low, now i just have to try and fix this annoying CPU fan noise, The M key is nice but it's not really silent, I also noticed that when the CPU fan turns on i can hear a high pitched humming sound whereas the GPU fan sounds like it's just pushing out air I tried switching the fans but the noise didn't change.

 

it's probably more at the vent level than the fan. Have you checked if there is anything visible there?

I'm currently at a steady frequency of 1.2Ghz 9x ratio with the M button enabled and the cpu fan is barely noticeable
I just decreased the max and min processor states to 20%

 

Yeah my min processor state is at 5%, i'll open it up tomorrow again and see what the noise is, i'll try switching the fans again, it seems like the buzzing/humming sound is coming from the GPU, it sounds like a luoud high-pitched whistle/hum when the GPU is on 100% load and the fan is at 70%, when it's on idle i hear a low humming sound.

i'm surprised the M button did something, when i press it is kinda loud like the the CPU is on full load

How to Reduce Fan Noise on HP Notebooks: Patching the DSDT table

from this I've found out that they have settled the fan to 8 speeds in the w860cu
0, 14%, 28%, 42%, 56%,70%, 84% and 100%
one solution could be to increase the threshold before the speed increase

 

M button as in, the "M" button on the keyboard or is it something else? and does this work on any clevo W860CU models (Sager, Deviltech, etc.)

 

Any news on controlling the fan speeds?

There was an unlocked BIOS posted in the ownerslounge, but it didn't seem to work.

 

no method for controlling the fan speed of 860cu

this is a EC problem maybe .

in my 45w 840qm (not your 32w 620m) , idle temp is about 45 Celsius and the fan speed is low.

When 50 Celsius , the fan turns to a medium-high speed .

sometimes 860cu's CPU & GPU fan both stop and they'll be very quiet , such as downloading in midnight .

cpu fan and gpu fan will interfere each other and the noise will be quite strange , though the fan speed is not very high .

On the other hand , when in games , both fans turn to a high speed and make harmony noise .

so this problem can't be solved .

 

I found a neat method to reduce the noise from the CPU-fan:

1) Enable the "silent" mode
You will see that this sets the CPU clock to about 1066MHz, while setting the fan at a constant speed.

2) Use ThrottleStop to set the multiplier to "Turbo"
This will set your CPU to the maximum setting, in my case 1,73GHz. The fan will stil run at "silent mode" speeds.

I found this to work great when gaming. It doesn't reduce the gpu fan however, and it is useless in light desktop use. It does however reduce the noise output while gaming.

I ran a OCCT:CPU test and found that the max temp increased about three degrees celcius with the fan locked.
