Hi all, I have recently installed a music application called Pro Tools. In order for this to work smoothly you must disable Hyperthreading and turn off the 'round smooth edges' under the display properties section in the control panel. My problem is that now my fan is constantly on and when I do anything that seems to require CPU power, E.G Click on a menu or open another application my fan speeds up dramatically. This is picking up on my recordings a lot. I want to avoid getting a silent box or changing the fan as I know that this fan is usually quiet enough. Is there anything that you would advise me to do, or suggest any reasons that this may be happening? I really dont want to enable Hyperthreading with the programme running as the 'Digidesign' - the company that manufacture the software strongly recommend that it's disabled. Any replies woule be greatly appreciated.
Thanks
L.Dudley
P.S Oh and is it dangerous for the fan to constantly be on?

"In order for this to work smoothly you must disable Hyperthreading and turn off the 'round smooth edges'"
Something does not seem right about the makers information. I can only think of one reason why they would recommend turning off round edges and that would be to gain processing power but this is in contradiction to turning off HT.
Is this program an older program like a 16bit application or something?
Try it with HT working to see if it is "smoother" then running with it off.
Regards,
Bryan

To quickly streamline the Windows XP OS for troubleshooting purposes, startup Windows in "Diagnostic Startup" mode.
blah, blah blah...Be sure to run "msconfig" and restart in "Diagnostic Startup" mode after disabling the drivers - if you wish to keep the OS streamlined.
Common hardware problems are linked to Wireless Network Adapters, RAID controllers, SATA drives and controllers, and Hyperthreading (Hyperthreading only applies to newer Pentium 4 processors). If you have any of these options you will need to disable them. Onboard RAID and SATA controllers as well as Hyperthreading will need to be disabled in the system BIOS - refer to your computer manufacturer or the motherboard manual for information regarding how to do this.

End of quoting.So it would appear the problems may or may not appear on your machine but if they do then you can rest assured it is related to their application. It appears too old for XP and HT.

Hi, firstly thanks very much for doing the research maybe HT isnt such a bad things for Pro Tools LE. It is Pro Tools 6.7 cs8 that I am using with a 002 desk. I notice that when PT starts and it gets to the DAE onjects bit under loadup it is very slow, and pauses for around a minute. I will now try enabling HT.
L.Dudley

Please do advise how it works with HT enabled for future and similar references.
Thanks and regards,
Bryan

Oh dear, I would if I could get into the Bios. I get to the blue HP prompt screen and press F10 (setup) and it progresses to the setup-load screen but just continues to load XP as normal. I have recently (yesterday) installed a new firewire card but it worked fine. Is there another way to access the bios please?
Thanks

PS does disabling the 'round smooth edges' really gain you that much CPU power?

"My problem is that now my fan is constantly on and when I do anything that seems to require CPU power, E.G Click on a menu or open another application my fan speeds up dramatically."
Your computer might be generating a bit of heat under load. Are you using some sort of fan control in BIOS to reduce fan speed under idle conditions? Maybe it's a quiet fan because it's being undervolted most of the time?
While the computer is off, use something small, and try to clear out the dust between the cpu's fan and its heatsink.
Consider either getting a fan controller to keep the fan at low speed, or upgrading your fan to a silent one.

To get into the BIOS...I'd say do it the same way that you did previously. Perhaps the HP setup screen runs a timer that if you select nothing then it goes to Normal startup.
Re: turning off round edges does not gain much so that is part of why I think it is odd for the makers to suggest it particularly in contrast to disabling HT.
After reading the makers page I see that disabling HT is suggested to prevent 'some' machines from having problems with it.
Bryan

No, this is the way I did it before. Now it is just going to the screen where you can go to safe mode etc. ARGH!

O.k, removed the pci firewire card and managed to get into the bios and disable HT. Also enabled the smooth edging. This made no difference and the fan is still on very much. I would be prepared to purchase a silent fan if I knew that the fan being on wasnt a problem. I mean the fan must now be coming on for a reason right? Meaning that there is a problem, if I purchase a silent fan then the problem is gonna still be there but I just wont be able to hear it? Am I correct in thinking this?
With HT enabled, I opened the ctrl+alt+delt box. The performance levels peaked up to 988-100 when openeing the programme, idled at around 44 with the programme just sitting open, and between 20-50 whist playing the song (song consisted of 13 mono tracks with around 4 plugins in total). The page file usage was around 393 leaving a low yellow line in the spectral graph.
However within the programme itself, the system CPU usage meter never went above 10%, the disk usage was around 10-15 and the PCI never went up at all.
So the fan is still on which can only point to the programme being installed. I even had the plugin bundle before (which in itself is twice as large in size as the programme and other application included in the Pro Tools bundle), and I have never had any issues.
Any ideas what I should do please?
Many thanks
L.DudleyPS Plus when I click on a certain preference within the programme my actual tower unit makes a system bleep sound. I cant understand why it would do this?

I am now a little confused.
I thought you were going to enable HT but have now disabled it.Had you disabled it prior to hearing the fan?
The best I can offer now is the following link to their knowledgebase:

Hey, finally got the HT enabled for definite and the fan is now back to normal and the programme is running just the same. Thanks. I am still getting a system bleep from my tower when I click on 1 simple thing however the program works so no need to worry.
Thanks
