Go into the power settings > advance settings. There is a fan option, and the choices are active or passive, you're likely on active.
Ever since updating to the latest BIOS I've noticed that The CPU fan seems to be running a lot more often under the same load as I had before. For instance right now the only thing running is firefox, and the fan kicks up everytime the processor use goes above 20% for more than 2 seconds.
Has anyone else noticed this?
I don't know if this is specifically related to the BIOS update because at the same time I updated I reinstalled Win7 and used the new HP drivers.

There is a constantly on option last time I checked, but that's all I know of other than what I noted.

There is an option in the bios as well regarding fan control. Other than that, use CPUID HWmonitor and see what your temps are at when its kicking in.

As I recall the only fan option in the bios after the update was "Fan aways on" or something like that. I had disabled that first reboot after the update. I think it's gotten better since I switched the cooling to passive. It all may just be a perception issue though.

Oh My gosh people...
I agree, the heat and fan problem on my HP Touchsmart is the worse thing about my Laptop and had I known it was going to be this bad, I would of never purchased the laptop.
But with that said... Trying to prevent your computer from using it's fan when it needs to is a bad idea. The electronic circuitry inside of computers need to stay cool as much as possible, if not - besides the obvious of your computer eventually "frying" itself and breaking, the tiny chips embedded on the mother board and else where will begin to expand when they are heated up. Over time of these chips expanding and then shrinking back to their normal size when the computer is cooled and turned off will also break the chips - which will also cause your computer to never be-have the same again even if you try to re-install your operating system from scratch, or worse yet your computer will never turn on again.
Just a little FYI here. I work with over 1,300 computers and servers and my work and I see this happen all the time when the fans on these things break or when they are place in a bad spot where the computer can't get the proper air circulation through it.

Up until I got my tx2z I used a big desktop as my main computer. It had like 5 different fans in the case (now I only turn it on for gaming). I still have a file server in the corner of my office, so it's not like the extra noise from the fan is that bad. Mostly it just concerns me when a computer acts noticeably different after a driver/BIOS update.
To me the increased fan activity means the CPU is being driven much harder now, or that the fan wasn't being run enough before.

Didn't recognize any changes in the fan behavior since I updated the bios and installed Win 7. The fan speeds up a noticable bit around 60°C and maximum speed is reached around 90°C. It showed the same behavior with Vista.

It's better now. I guess on the first reboot after upgrading the BIOS I had disabled the "Fan Always On" option. Having it enabled keeps the CPU a few degrees cooler on average. It's just enough that the fan kicks into high less than half as much.
Quick observations:
Idle temp with always on disabled: 57C
Max temp observed under normal use: 66C
Average: 59-60C
Idle temp with fan always on: 50C or lower
Max temp observed under normal use: 65C
Average 55-57C

I went into the power management scheme and lowered max and min cpu clock for plugged in and battery. So my max is now 80% plugged in. I'm getting idle temps of 55c and 65c load now, but before at 100% it was getting in the high 80's low 90's under load. Totally unacceptable! This is a mobile chip, right?
Anyways, I'm running the zm86. I just flashed to f21. Was there some kind of reset I should have done (like clear cmos on desktops) after flashing? I notice no changes in fan speeds or anything for that matter. Couldn't find a revision history on the bios either. I really updated to fix the jumping pen cursor problem. But still, no fix.

The only reason I had noticed any change at all was because I changed the BIOS fan setting *from* the default. Past that it doesn't look like the new bios actually changed fan operation significantly.
However I did notice one other thing. The temp changes I noted above were with the tablet plugged into the adapter. I also have a quickdock. After resetting the bios to default settings I noticed that when connected to the dock the fan never speeds up anymore. It stays at the same speed all the time. This is letting the temp hang out at about 75C under my normal usage. When I initially noticed the difference in fan operation it was with the dock attached. I made other changes in windows, but only to the battery power setitngs. I'll have to change the BIOS fan option back to disabled and see if the dock still acts the same way when I get home.
Although, I'm still thinking about taking the thing apart and regreasing the processor. I've heard HP isn't the best about properly applying thermal compound, and the stuff I've got left over from the last computer I put together is probably better than what they used anyway.

I swapped the thermal paste on mine, helped quite a bit from the crappy stuff they had on there.

Well, my warranty expired a few weeks ago. What kind of thermal paste do you recommend?
October 26, 2009 7:23 PM
Honestly, almost any 3rd party grease is likely to be better than the generic stuff most PC manufacturers use. Most of the time though I go with Arctic Silver. Although I've never regreased a laptop processor before, I'm not sure if it's better to use one type or another.

Read the article if you want the exacts, I would hazard a guess that this would be particularly helpful on this computer, as it has a tendency to overheat quickly.

I would suggest IC7 paste personally unless you really want to experiment with making it yourself which is a risk due to separation of the materials. I have had excellent results with it.
