Samsung x360-34P Fan noise

The fan on my x360-34P is almost constantly on and I was wondering if anybody else was having problems similar to mine. I didn't notice the fan being on this much when I first got it, but then again, I could just be noticing these things now...

 

CPU usage seems to vary between 4% and 10% when idle (jumps to 20 or 30% infrequently). Using RM clock, VID: 1.0750V, Core temp is around 33 and 34 degrees Celsius. CPU load 68% OS load 5.4%.

Core temp seems very low..so why is the fan running?

 

Does this happen for all the operating modes (silent / normal / performance) you can step through using Fn+F8?

Are you running the latest BIOS?

Hi John, I know it's not the right place to ask this question but can I do the "undervolting" on the CPU of X360 and does it worth to do so ? I know you have practiced this for years. Thank you.

 

That is a relevant question since undervolting should reduce the heat and, therefore, the fan activity.

Yes, you should be able to undervolt using RMClock. The X360's CPU and chipset is the same family as in my Dell E6400.

However, while undervolting should be able to drop the full load voltage and therefore heat, Intel locked the minimum voltage. It's worth trying. As you say, I've been doing it for years (more than 4).

Hello. I have downloaded the newest BIOs. The fan does not seem to turn on as much in silent mode but the core temperature rises.

 

Yes, silent mode raises the fan trigger temperatures so you get a slightly hotter computer but less fan activity. Silent mode may also limit the maximum CPU speed in order to reduce the heat being generated.

I had a question about core temperatures. When I play games, the core temperature seems to rise to 45 degrees. Do you think it would be damaging for the computer to play games for an extended period of time?

Also, for other x360 owners, is the fan being on almost constantly normal for you guys as well? I'm just worried my laptop fan might be defective. Fan turns on around 35.5 degrees, turns off around 33.5 degrees

 

45C is relatively cool. It is quite common for CPUs to run at around 70C when under full load and they should operate safely at 90C (but are usually set to shut down as they approach 100C).

The fan coming on at 35.5C is quite low. What software are you using to measure that temperature? You may find another software or even a different version of the same program reports a different temperature. However, that difference is likely to be only around 5C.

There is normally a bigger range between fan on and fan off temperatures. It's possible that Samsung have done the same with the X360 as they have done with the NC20 and incorporated a silent mode option in the BIOS. See the attached for a description and press Esc or F2 at the Samsung splash screen to enter the BIOS.

Hello. I am using RM Clock to measure the core temperature. I'm assuming it would be safe to run the laptop in silent mode at all times? Thanks for all the help.

 

Might be a bad thing to do, but I used the dirt buster bottle on my fan when it made a noise and it just blew some dust away. could be the case for you too, but kind of risky

 

Is that the silent mode in the BIOS or the silent mode provided by Fn+F8? The former runs the fan continuously, so it may wear out faster (but unlikely to be a problem if it is running slowly) while the latter raises the fan trigger temperatures and may slow down the CPU.

Use whatever suits you. Samsung are providing the options so users can have more choice.

I don't even bother using RMClock as it barely does anything for this laptop. You'd probably get 5 more minutes of battery life out of it only at MOST, since unforunately the board is voltage locked so we can't go any lower than the default voltages which are still super low at full load. Sigh...I know they can go lower....I miss the days of the Dothan Pentium Ms and going to 0.700 volts. RMClock barely does a thing for the laptop in my sig as well, it is locked to a min of 1.0V, although I got it undervolted to 1.3 instead of 1.5 at full load, but that's hardly significant - very dissapointing. It seems RMClock is getting less and less useful for newer notebooks, but is great if you have Pentium Ms/Centrinos around. I still have 3 of those laptops lying around and did some massive undervolting - boy that was fun. Less heat, noise and bettery battery life!!!

Alas....those days are gone. Oh well. I get nearly 9 hours + of battery life internet surfing and with productivity apps on the x360 samsung, and about 7 hours if multimedia is used - highly impressive. I think the X4500 GPU basically offloads all the decoding for video so that saves CPU and battery. You can also set different power/performance settings with the X4500 drivers for more power savings or more performance, but so far I've always left it at max power savings and minimum performance for everything including games and movies including high def.

 

Hello,
I've spotted this thread when searching for the people with similar problem as mine and since there is no specific thread for fan/hard disk noises, I allow myself to post my issues here.

The problem I have with my X360 is the grinding noise (loud!) coming from my hard disk (120GB Toshiba MK1216GSG). I noticed that it only starts when the cooling fan turns itself off. The laptop then becomes warmer and when the fan kicks back in, the disk noise automatically disappears. And so on.
My question being then: is it possible to turn the fan on permanently? The fan itself does not make a lot of noise and I definitely prefer it to the angry, erratic and loud noises coming from the hard disk...
Also, can it be a general problem with electric components? (logically, if the fan kicks in and the disk noises disappears, the more power is consumed by the fan, maybe it counterbalances the power provided to the disk?).
Thanks for any useful input.

Cheers,

Christof

 

Does Fn+F8 offer a silent mode option? On some other Samsung products this keeps the fan running slowly instead of switching on and off depending on the temperature.

However, your underlying problem is peculiar. I've known noisy HDDs, but not encountered one where the noise reduced when the fan is active. I presume that you have satisfied yourself that it is not a case of the fan noise making the HDD noise less noticeable.
