vaio fan control

Hi,
Is there any control program for manually control the fan speed?

 

Try Speedfan

 

Yeah, XP Vaio Power Management have it!
Vista Power Management don't.

 

Hi,
I tried speedfan and you can see that it does not recognize any fan!


Vaio power management does not make any sense. I used it but fan noise does not change

 

anyone have any program that reduces the annoying whir of the fan?
I don't care about heat that much b/c it's already incredibly hot anyway.

 

slow or shut your fan off and it sounds like you'd be heading for a meltdown!
Maybe a disassemble and clean is in order to reduce heat and maybe fan noise.

 

You SHOULD care!

The issue, of course is not about controling the fan. One should not control the side effects, but the source of the problem.

I think it is a general issue that Vaio are very good laptops, but they make too damned noise in their fans. It is damned stupid that the CPU is at 10% usage, and still heating like hell.

I have been researching this and found an interesting approach regarding CPU frequency. Take a diesel engine in a bulldozer or a farm tractor. They work at full speed or minimal speed depending on the need for binary (sorry, I am an mechanical engineer). The issue in computers is that CPU is always working at full speed, redline, even in standby.

It seems that there are ways to scale down the CPU speed to half frequency for average tasks and some dudes only use full power while ripping DVDs.

I am still trying to find a windows application to scale down and up the CPU frequency so the heating issue is solved, therefor the damned fan noise.

Help would be appretiated.

Never had a tool for controlling VAIO fans but yes, controlling the (heat-)source works fine - 100% stable when done correctly.
Using a tool like RMClock you can undervolt the cpu and/or specify cpu frequency via profiles. Switching from power/noisy to slow/quiet takes 2 mouse clicks once you've configured it to your needs.
Works well with standard Intel Core 2 Duo and older Pentium M models at least.

Copy of my post from http://forum.notebookreview.com/archive/index.php/t-210325.html :

Undervolting is a NECESSITY for me. My notebooks are much quieter this way and I can run lots of CPU intensive tasks like x264 video encoding in the background without disturbing me at work. Should save same energy, too.
Personally I use RMClock for years (startup via task scheduler to avoid UAC prompt) and Stress Prime 2004 Orthos Edition for stability checking.

Not sure how you are determining that this is a generic problem with Sony laptops, but my FZ190 is NOT exhibiting this at all. It cools right down and the fan is quite when the CPU is at 10%.

Sony is already doing this. Again, on my FZ190 the cpu clock is throttled back when the load on the cpu diminishes. The CPU is NOT working at full speed all the time.

^ unfortunately my CR240 does not scale back the speed...it runs at 2ghz regardless of load, or even power profile settings. With my old dell with Centrino and XP, changing the power profiles would change the processor speed. I really liked that since it saved power and definately kept the temps down. But its also nice to be able to control the fan. I always liked to keep the fan on highspeed while the computer is stationary in a place where it doesnt matter about the fan noise. Keeping the processor cool is very important to me. And i dont have a chill pad for space reasons.

I wish windows had something simple to control it, or optimize it, at least for my notebook.

 

Well Gary, all of my friends that have a vaio, have this issue, and reading online I sense a majority complaining. I guess a minority as you, or in latest models might have solved this. But sorry for jumping to conclusions.

Meanwhile, I noticed that I had selected the Power Managment on PERFORMANCE instead ADAPTIVE which reduced this a bit, but still annoying.

I trust sony as high quality products, so I trust that issues like this will be solved. Since Compaq did not sells replacement hinges for my laptop, I never want to hear about Compaq/HP anymore. I trusted Sony to be above average. When I compare the speed noise to that poor 900MHz Celeron, Compaq takes the advantage.

I wonder why Sony does not advise regarding this, or just offers earplugs to the majority of us...

PWR:
Thanks for your input. I shall stay in touch to check how one can do this. Let me check your links. I installed SpeedFan 4.33 so this issue of scaling down the clock speed looks very interesting.

 

I just tried for a whle RightMark CPU Clock http://cpu.rightmark.org/ that PWR suggested earlier in the thread. It works well, just takes a while to tweek the stuff. But my question is, how slowcan the new core2duo processors drop down to? Even with cpu mangemnt programs, i have not been able to reduce the processor below ~1100 mhz. I have the 2.0 ghz T7250. Perhaps cutting about half the speed is as low as it can go?

And wow that sucks that compaq didnt have replacement parts. Sony has parts for just about anything, but at a super pretty penny price. haha

 

I just did the same. Installed it and am trying to understand this without damaging anything.

I am using FanSpeed 4.33 and CPU clock Utility. But I only noticed a slight increase in heating monitoring the temperatures. But its interesting to see it loweres the frequency.

Perhaps we should start another topic just for debating the CPU clock issue so we wouls debate what tune ups we are doing and what improovement we found.

 

A new thread may or maynot be necessary.
At any rate, you got fanspeed to work for you? when i installed fan speed i couldnt manipulate fanspeed because it didnt recognize my vaio's fans.

 

A few thoughts and observations:

I always use the Performance on Demand power management setting in Windows. This allows the CPU speed to be adjusted according to the workload. If the CPU still runs at full speed then make sure that SpeedStep is enabled in the BIOS. The Maximum Performance setting keeps the CPU running at full speed.

Thin notebooks tend to have noisier fans because they have to be smaller and spin faster. Unless the fan is blowing out cold air, the challenge is to reduce the heat, not slow down the fan.

The latest RMClock beta (go to the RMclock forum for the link) has good support for the Intel dual core CPUs including the Super Low Frequency Mode. In fact, it has extended that mode so that (a) the voltage can be used for any speed (subject to stability) and the SLFM frequency can be as low as 600Hz. The T7300 in my Zepto 6024W spends much of its time ambling along at 0.9V, 600MHz, ~52C with the fan off.

A dedicated GPU is another source of heat which may be bigger than the CPU. This may cause the fan to run even if the CPU is on idle.

Thats good information John. My question is...how in the world can you access the Vaio Bios? I dont see any prompts telling me to press any of the "F..." keys like most computers i've dealt with do.

 

F2. But don't expect to find ANYTHING once you get there. There are virtually NO options to play with. And absolutely NONE in regards to the CPU.

Gary

 

Thanks gary...and you are most certainly right about there being virtually nothing in there to tweek...haha. At least it shows that i have 4gb of ram! haha
So like is it a default for the fan to start running when the processor temp reaches 116? I find that somewhat high of a temp...I say sony needs to release some bios updates!

 

my sony TZ has the option to control the fan, 1 (silent) 2, 3, 4,5

 

Well I basicly just use fanspeed to monitor temperature... But it did also not recognize mine.

 

So I guess I am also just using RMClock to monitor the CPU frequency. But it is nice to find out that the vaio itself already reduces the CPU frequency(speed).

Well, I learn with some decades that its better to observe firtst. Nice to find out about this, I was not sure what the adaptive option was all about. Good to know.

This is the kind of info I was seeking.

Of course!!!! but always important to remember, some people might do stupid things.

Humm, I was looking at those tune up. So, is it safe to try smaller voltages and so?

Sorry for asking, but what is GPU? Graphics processing unit, perhaps....

I do notice that on my vaio, a big big source of heat is on the opposite side of the fan. Probably the Graphics processor, which I understand to share some of the RAM.

I think I might have reduced some heat removing the optical disk drive (and save some weight). I use it only a couple of times per month...
