T61 running hot after cleaning and attempt at undervolting

I recently dusted off the insides of my T61 using a compressed air can and then I tried undervolting it but I gave up because I wasn't really noticing any change in temps (I was probably doing something wrong) but now my T61 runs hotter than before. The CPU used to idle around 45 deg C but now its at 55-60 deg C. Any suggestions on how to fix this?

Thanks,
Plat

 

Did you remove the heatsink to clean it or did you leave in place?

 

wow 45C to 55C?

Make sure you have defaulted the clocks/voltages. if not sure, uninstall rmclock.

are you sure its not because we are in summer now? are you comparing winter temps to summer?

 

Nope, I didn't touch the heatsink I just moved the keyboard out of the way and dusted everything off

 

@batman: I uninstalled rmclock and no I'm not comparing summer to winter temps all this happened within about 2 weeks

 

Are the fans coming on?

 

are you using TPfancontrol? if so make sure its on bios and not smart mode to return it to stock.

 

I'm not using any fan control either, they come on as usual but they only bring the temp down to about 55 then cut out

As for the uninstallation of RMclock I just deleted the system folder b/c there was no uninstaller and thats what the readme said to do for uninstallation

 

what program are you using to find the temps?

 

CPUID hardware monitor

 

ok. did you do anything to the GPU? Overclock? new drivers?

 

I didn't change anything else the only thing I did recently was upgrade my HD to a 7200rpm drive but the CPU temps were fine after the upgrade

 

any suggestions for other programs I can use to double check the temps?

 

cpu and gpu share heatsink so anything that taxes one will increase temps on the other. check taskmanager to make sure no background programs are taxing your system

when you say you changed out the hard drive, I am assuming you did a clean install. are you 100% you are using the same GPU driver before and after? would it be possible to slap in the other hard drive and check temps?

that way we can see if its a software setting or if you have a hardware issue

machine should be on flat surface with fans not blocked.

 

tpfancontrol. it will also let you control the fan but you can leave it in bios mode to let the fan run normally

 

when I swapped out the HDD I used acronis to copy all the data from my old drive to my new one so I didn't have to a clean install but I can't put the old one back in b/c I already wiped it clean and put it in another computer.

the T61 is on a table with nothing around the fans to block air flow

thanks I'll give tpfancontrol a try and let you know what it reads

 

one more thing. I heard that if you (somehow) you get a new cpu (t8100+) with an older motherboard (for say an t7500) that there is some error as they went form analoge to digital temp monitors.

i think it was on the forums at www.thinkpads.com

also, redo your power manger settings. You might have to reinstall the energy star profile. maybe rm clock has overwritten certain settings

good luck, hope its not a hardware issue

 

thx batman I'll see if that makes any difference, if not I'll just do a clean install of vista I guess

 

GOOD NEWS! it turns out I hadn't completely uninstalled rmclock, I did a search and found it was still on the system (I must have only deleted the shortcut or something...what a dumb mistake) and now the idle temps are back down to 43 deg C for CPU. Thanks all!!!
