Problem solved - faulty memory was the culprit. The CPU and GPU were probably not overheating although it did not do any harm to replace the thermal pads with Fujipoly. I pulled one of the 2GB memory cards that I had installed a year ago and this old CF-30 passed the memtest86 memory test, plays Net...

I think droppointalpha may be on to something as the computer hung when running the Panasonic Diagnostic Test, specifically the Memory Test. Passed all other tests including Video. I then ran the Memtest86 application and it also crashed the computer but not before reporting some memory errors. Perh...

The pads were the best from Fujipoly with a thermal conductance of 17.0 W/mK (they also come in lower 6 and 11 conductance variants). I suppose it is possible the chip is not making good contact but did check to see that that the chip left an imprint on the pad before putting the computer back toget...

OK, overheating is still a problem as the new navigation software I am running on this CF-30 is even more taxing on it than video. According to the GPU-Z utility I downloaded, the load on the GPU is about 14-16% running Netflix but a whopping 60-70% running Nobeltec TimeZero, the marine navigation p...

Well I took the plunge and pulled the motherboard and replaced the thermal pad on the GPU chip as well as the one on it's thermal tube. The old GPU pad was dried out but unfortunately, marginal improvement with the new one so this CF-30 appears to be destined to being a non-Netflix device. The CPU i...

Thanks Teo, Have downloaded the CF-30 service manual and am thinking about it. I'm sure you are right about this being the cause of the overheating but it is a little more dis-assembly than I was prepared for. There is a YouTube video describing replacing both (CPU & GPU) thermal pads on a CF-29...

Works better but still crashes - CF-30 will now run about 50 minutes of video instead of the 10 before. I purchased new thermal pad material from FrozenCPU plus the solvent used to clean and prep the surfaces. Ended up putting two layers of the 1.5 mm pad material on the CPU heat sink to get good co...

What are the specs for the thermal pads for a CF-30? I see some threads on the CF-29 that call for 1.5 mm thick pads. Frozen CPU has these:

Fujipoly / ModRight Ultra Extreme System Builder Thermal Pad Blister Pack - 60 x 50 x 1.5 - Thermal Conductivity 17.0 W/mK

Would that be enough?

In response to safn1949, the machine is definitely hung - video, audio (usually unpleasant tone) and all other apps. Needs to be shut down from the power switch. I think it is certainly overheating rather than software of bottle-necking as it can go for up to half an hour of video play if it is sitt...

My Cf-30 MK 1 is six years old now, still giving great service on our sailboat and I with a little help from this forum, have upgraded it to Windows 7, 4 GB of ram and most recently, a 500 GB SSD. The later was one of the best returns on $ by the way. One problem - playing videos. I have a VGA link ...
