R50e (Celeron M) - heat, fan, experience and questions...

[Leonche]

Hi,

I installed recently RMClock on my Thinkpad (Celeron M) in order reduce heat and to make fan running not so often. Till now the cycle temp is 61 Celsius (fan starts) and temp 56 Celsius (fan stops). And this every 3-4 minutes - stop and go constantly. It's not too noisy, but it's annoing. Now - I installed RMClock and set ODCM (OnDemandClockModulation) at 50 % with the following result. In Office use CPU temp rises much slower and ramains stable at 51-52 Celsius and so fan NEVER starts - so I had a quiet laptop for more than an hour!!
At the end however I was a little worried about not too overheating the machine and turned RMClock off. Why? First, I had the impression that the laptop was hotter after one hour of working without fan (BTW this sounds logic now, but some days ago, when I experinced it, it was a little horrible) Second, I read in a forum that actual heat in Thinkpad R50e comes more from the GPU (Northbridge) and not so much from the CPU, others state that forcible ODCM makes RAM modules become hotter - so heat rises.

My question is - is there a risk in reducing the cycles of Celeron M by ODCM for a longer period of time? First of all for the CPU itself (I found nothing about that in the web)? Second, is there an impact for the RAM modules by using ODCM? At the end TM1, on which is based ODCM, was designed as an extraordinary measure (like a sudden stop of a train brake) and not for constantly stopping CPU cycles.

Thank you in advance!
Leon
