XPS 13 9305 - can I use i7 fan/heatsink on i3?

The system board died on our XPS 13 9305 with an i7 processor.

I got a replacement board but it's i3 based.

The service manual shows two different procedures for the fan and heatsink - one for the i3 and another for i5/i7 based systems. Looks like the fan/heatsink is one part for the i5/i7 while the i3 seems to be two parts.


Can I use the i7 fan and heatsink with the i3 system board? I put on some thermal paste and it seems to work. I ran Prime95 for a few minutes and the temp stayed in the 50's.

I was able to run Prime95 for longer now that I have a power supply.

It gets to 90-95 then settles into the 80's. I ran this for 2 hours.

I then stopped Prime95 and it went back down to high 30's low 40's.


I guess it works.
