Laptop fan question

I recently got a Zoostorm laptop.

CPU-Z says Clevo W240/W250/W270

It came with a Celeron 1000M CPU, and yesterday after stress stressing it in CPU-Z it reached 80+ degrees and was climbing, and there is a fan, but it was almost silent.

HWMonitor showed the package using ~15W but the TDP is 35W

I was considering swapping out the 1000M for an i5-3340M or similar, would I have any issues with this? Would I need to buy a stronger fan?

 

Fan rules are coded into the BIOS and are usually based on temperature with corresponding fan speed (with sometimes a time delay to require time over the temperature threshold to stop brief spikes in the CPU activity triggering a brief faster fan speed).

I am surprised to hear that the fan was almost silent with the CPU temperature of more than 80C. While the limiting temperature of the Celeron CPU (Tjunc) is 105C, most notebook manufacturers design cooling systems to keep temperatures well below 100C. It's likely that your fan will noticeably speed up at a temperature just above whatever you observed but if it was running quietly then it will have plenty of reserve capacity.

I would therefore consider it most likely to be safe to use a faster CPU provided it is compatible with the socket (FCPGA988) and is supported by the BIOS (ie offered in another version of the same notebook).

I've seen a few notebooks set to rev up the fan considerably at 90°C for the sake of keeping things silent running unless you're really stressing the system.
