Appropriate running temp for R60?

[ajsanjuan]

Hi, I'm running a seven year old R60, originally a 9457 chipset with Intel Integrated Graphics, 1.66 GHz Intel Core Duo Solo T2300, 80GB HDD, 2x512MB RAM and Windows XP Professional. Since then, it has been modded over the years to a 9462 chipset with 'standalone' ATi Mobile Radeon X1300, the same transplanted 1.66 GHz Intel Core Duo Solo T2300, 320 GB HDD, 2x2GB RAM and Windows 7 Enterprise 32-bit.

My question involves the various system temperatures, especially for the cpu and gpu, which seem to be running a bit high since I switched out chipsets three weeks ago (mid-May 2013). I understand that switching from integrated video to a dedicated card would increase temperatures somewhat, so I have to ask what the normal parameters should be.

Idling on the Start menu gets cpu temps around 55-70C, with gpu temps in the same range.
Ordinary Internet or word processing produces cpu/gpu temps in the range of 60-70C.
Computer games (moderately graphic intensive and circa 2006) achieve 70-95C at which point the computer either crashes instantly (complete black screen) or produces an NMI Memory Parity Error BSOD.

I realize that in switching to a dedicated video chipset, and having to transfer the RAM, heatsink and CPU across bases, I may no longer have the correct heatsink design (there were two listed in the HMM, one solely for the CPU and another for both the CPU and GPU - I have the latter from my old 9457). I also wonder if I should have applied additional thermal paste to the heatsink/CPU interface during the operation.

What are your advice, guys? I appreciate the help in advance!

Thanks,
Andrew

BTW, the temperatures stated above are with TP Fan Control running at "Smart", with additional cooling provided by a USB plug-in Belkin Laptop Fan. On the most graphic intensive programs (i.e. games) I even toggle the TP Fan to 'disengaged' manual on the '64' setting. Alas, it doesn't always help.

Welcome to the forum!

First of all, you need a different heatsink assembly for the new ATi board. Yesterday.

Secondly, once you obtain it, clean CPU and GPu from any residue and apply thermal paste on CPU only, GPU should be covered - if I remember correctly - by thermal pads which don't require additional pasting.

And yes, those temps are quite high. Don't stress the machine out until you've swapped the heatsink.

If the combination heatsink from the old 9457 is no longer appropriate, then I assume that the other heatsink, that is, the one only covering the CPU should be ordered. How then would heat be dissipated from the GPU if there is no longer a heatsink over it? Just curious...

Your assumption is incorrect, since no such heatsink exists for the R6* series. There are other aspects which are different, though, between heatsinks meant for integrated and those for discrete GPUs.

The correct FRUs for your "new" heatsink are: 41W5269, 41W5270, 41W5271.

But the above heatsinks look identical, at least visually, to the one from my 9457. Are there any unseen engineering differences in the designs between these heatsinks and the visually similar one from my 9457?

Generally, fans for machines with discrete graphics top at higher speeds.

Yeah, they all look similar. It doesn't mean they're exactly the same.

With all of that said, a thorough cleaning of all the surfaces and proper paste application along with fitment of the heatsink are the most important aspects of keeping the machine as cool as possible.

Thanks, that answered my question - I guess visuals can be deceiving after all! I'll order the proper fan and some Arctic Silver ASAP, though I could probably keep my machine cool enough as long as I don't stress it too much...no gaming until things are repaired! (Right now with Firefox it's running at a safe 65C cpu/71C gpu at 3275 RPM plus the laptop pad.)

Thanks again for your help!

Oh, on one more note, which of the three combination cpu/gpu fans would you say is most effective (e.g. fastest fan speed and/or heat dissipation), the 41W5269, 41W5270 or 41W5271?

The only difference is the manufacturer.
Toshiba 41W5269
CCI 41W5270
Furukawa 41W5271

I prefer Furukawa.
