    K, those of you who have an Asus C90s or have had one, would know how it heats up really quickly even when idle. My GPU hovers around 70 degress when idle, rises to 89-90 when stressed. Done a couple of stuff to cool it, like switching out the stock thermal paste on the GPU&CPU for MX-2, cutting out a hole on the base of the assembly door and getting a laptop cooler.

    Undervolting it doesnt seem to help much as seen from the comments in this NBR thread:

    http://forum.notebookreview.com/showthread.php?t=228367&highlight=undervolt+c90s

    However, what i did discover is that when i was stressing out my CPU with Orthos, the fans kicked in really nicely, lowering GPU temps by about 8 degrees to 62 degrees.

    Is there a way to get those fans maxed out all the time, and not just when the CPU overheats?

    A guide to do something like this would be great:

    70 idle? 90 stressed? You have a cold C90S :p

    Thanks for the tip but this is something I said a year ago :p

    Having a nice way to manually control them would rock.

    Heh and i thought mine was running way too hot. PM'ed Ziggo0 over at ocforums who did that sweet mod to his fans, ran 12V through them. Seems he's more active over there than here. Hope he replies soon.

    Your idle gpu temp seem too high especially if you are down clocking. I'm running around mid 50's with my setup & using the turbo gear to down clock. I do have manual fan control for the gpu fan but do not use it often, Ziggo's guide is probably more than enough to give it a whirl.

    One of those four fans in the back of the C90 is for the GPU.

    Dont worry what everyone says, 70 to 80-90 are more than fine for the C90S. Also know that temperature depends a lot of the environment you are running your laptop. I don't recommend any mod even though Ziggos was a good one. C90S was made that way, to run at that high temperature even though it would have been nice to get lowers ones but when I contacted ASUS Tech support a year ago about that their replied was 66 to 75 for iddle and 85 to 98 stressed (could go little bit higher on some games) SO yours it is just fine so be happy about what you have. I had my C90S for more than a year now running on those same temperatures and it is still working fine ;)

    best regards,

    RG
