Hi,
I'm running XP on my N10J and I've run into a snag, any time I watch a movie the GPU gets worked and the CPU is pretty much idle. The GPU rises in temperature and the fan does not react.
As a result I've seen GPU temperatures of 105 degrees C before standby or hibernate cuts in (depending on whether hibernate is enabled)
How can I fix this?
Thanks
(there is another post with the same problem but no solution here: http://www.n10user.com/viewtopic.php?id=1402)
You could fool the CPU in thinking it is working. Rightmark has a tool named RMClock, and it has a special little program built-in that makes your CPU believe it is working at full 100% while in fact it's doing nothing. I use this to keep the voltage up at maximum at all times, so my OC at 2.2Ghz isn't jeopardized by Intel's SpeedStep lowering the voltage. I guess you could use this tool to keep SpeedStep from turning down the fan?
You can find RMClock here: http://cpu.rightmark.org/products/rmclock.shtml
I believe the little algorithm you need is called the 'HLT-command', but I'm not sure.

Yup, it is called the "HLT-command".
Though I'm not sure if fooling the CPU will cause a change in fan speed. Try it and let us know.
It'd be useful if someone knows what actually affects fan speed in N10. Sometimes my fan kicks in only after CPU reaches 70C.
On a side note, OC @ 2.2Ghz? Wow. I have stable OC @ 2.06, above that, the system becomes unstable. What was your RAM?
Just using stock RAM here still 
Though it helps to know, the little sticker on my RAM-module identifies it as being a DDR2 PC6400, which makes it certified to run at 800Mhz. The N10 only runs it RAM at 533Mhz (or was it 667Mhz?) so there is some head-room there.
And 2.2Ghz isn't very stable for me, I use it mainly for non-crucial tasks that need to happen fast. 2.0Ghz is rock-solid, 2.1Ghz is solid enough for gaming. Like Minecraft 
Hi,
RMCLock doesn't work as far as the fan is concerned. It does mean with the added voltage that the CPU idles with the temperature a little higher so the fan is running more but the fan still only kickes in when the CPU hits 70.
I don't really want to have to make the CPU hot in order to run the fan, I like to be nice to my hardware. Especially when running on battery this just seems like a waste of power.
I'd also be interested to know what GPU temperatures you'd consider normal as mine seems to cut in standby at around 95 or 90, maybe a little higher. I've attatched a screenshot of the temps and fan speed shortly after this happened.
I wonder about a setting I saw in windows 7 to do with Active and Passive cooling. This still ran off the CPU but it went up to 300 rpm when spikes occured and the CPU went to maximum clock. If I could do that setting in XP I could possibly combine it with RMclock to keep the fan at 300. Anyone know how to apply that setting in XP?
I still want a way to make the fan react to GPU temps but I'm open to other options
@darkjeric
I see. I use a PC-5300 RAM. After reaching 667 Mhz with OC @ 2.0 Ghz (yup, N10 runs the RAM at 533mhz, but remember there were some cases where the FSB:DRAM ratio was 2:5, running RAM at 667Mhz without OC.), it starts to force its limits, and fails anywhere above 2.1 Ghz. Using a PC-6400 RAM may give more head-room compared to PC-5300.
@spidermagicat
Have you tried messing with PowerMizer settings? If I remember correctly, enabling/disabling Powermizer affects the fan speed. Maybe that would give a solution?
Do not take my word for it, but I guess anywhere below 100C is acceptable, though getting close to 100C may affect the GPU. I don't know if there is an exact temperature, or if it changes from GPU to GPU.
Where did you find that setting about cooling in W7? I'd like to check it out.

You go to power settings and select "Change Advanced Settings" I think.
It's the setting in the screenshot.
I found the fan would go to 3000 RPM or there abouts any time the CPU was spiked when it was on Active which was ideal.
I do have powermizer enabled. Without it enabled the GPU temp climbs regardless of whether it's in use and the fan still wont kick in. It seems the only way I can protect the graphics card is to torture the CPU into going above 70 degrees.
I've sent a technical enquiry and been told to send it in for RMA, I probably will soon but as the motherboard was replaced through RMA (due to the power socket failing) in January I don't think it's a hardware fault. Do you know if they'll do any software fix other than simply putting it back to the default vista setup?
I don't know if this is a hardware problem really, it's just the BIOS that only kicks in the fan when the CPU is getting warm. Since the Atoms are such cool processors (in the literal sence of the word) they only get hot when they really have work to do. I can't say I ran in to this problem already, but then again I'm running Win7 which already stresses the CPU more than XP does. That and I usually only use the 9300M to watch HD-movies (or Youtube HD) or play games, which tends to stress the CPU enough to let the fan kick in.
Maybe you could lower the GPU-clock a bit to let it run cooler? If you're just watching movies on it there really is some head-room there. What are you using to watch movies with, and are you watching any HD-stuff? If not, the Atom+Intel IGP can handle most SD-video fine.
@Crossbourne: I knew about the ratio. I had it one day before I flashed to the newest BIOS, then it was gone (sad face)... But I don't think it has anything to do with RAM past 2Ghz, as I've never gotten mine above 2.2Ghz even with a DDR2-1066 certified module in it. I think it's either a component on the motherboard or the Atom itself that gives in at that FSB-targets.
Thanks for weighing in with this topic. After watching temperature fugures closely during the last incident I now know almost exactly what is going on.
The fan only responds to the CPU diode temperature. When this hits 80 the fan will kick in, it will cut out when it dips below 70.
The lowest temp I've seen standby cut in on is 85, If I contimue to try and watch the film the GPU has gone as high as 90 with the fan still not kicking in. I decided not to stress things furthur.
I am using the laptop to watch SD movies mainly but I watch 720p stuff through the HDMI and occasionally 1080p so it's an issue.
I think I'm a victim of making my laptop efficient enough not to stress an atom CPU when watching 720p, in a way I'm slightly proud of myself. :-D
It's been suggested that I send it back into warrenty and I'm wondering what temps your GPUs run at, if 85 is in range for GPU then it is something wrong with the mainboard and I'll send it back in safe in the knowledge that there is a real problem.
I'm also wondering if different graphics drivers may help if you're using XP what version are you using
Thanks
