It was my intention to use my laptop for recording and sound production. The Dell laptop I got was ridiculously noisy, even though it had a solid state drive.
In my opinion, it is clear that Dell have a design error with the particular model I had. It could be to do with the way the fan is mounted. It could be to do with the type of fan (cheap?). Either way, the problem was intensely annoying.
I returned the Dell Laptop. The situation was ridiculous.
I bought an equivalent specification HP laptop and have not had a problem with fan noise at all. Of course, there was all the hassle of transferring the software over (A long process). It was worth it.
I'll never buy Dell again.
After a few months, my HP laptop continues to do what I want - run quietly, perform well and allow me to make music.
My advice is don't go wasting time over this situation - it's a design error, nothing will correct it. My advice: return or sell your Dell, buy an HP. Sorted.
