Lagging HP ZBOOK 15 workstation solved

I suffered a slow i7 workstation with 32Gb RAM and solid state disks. Its fan is noisy. It was like this since I bought it second hand. So I thought it was normal for HP workstation since a few reviews also mentioned that Zbook can get hot and noisy.

It gets worse and worse until it becomes unbearable. I suddenly remembered my Asus A42 with i5 which because so slow despite constant defragmentation, until it failed to operate entirely. Its CPU burned. I replaced it with an i7.

I should have know about this but was in denial mode. Too lazy to open up the laptop until today. After a few mistakes, everything works as usual and cool. Luckily I have just bought a few pieces of 1mm and 0.5mm thermal pads and I still have spare thermal paste.

The ideal temperature of this laptop is now 50 degrees. Before that it was 80 degrees. It frightened me and may end up losing its CPU again.

Now it reminds me of my office PC. It could be due to worn out thermal paste also.

Not really solved. Only problem reduced but today it is much better. 2/2/2020.
I just go to BIOS setup and tick the fan always on on AC supply.

Laptop is faster than Desktop

I had been most confident that my desktop PC is much faster than my laptop or notebook.
Although I read a lot of benchmarks, and compared benchmarks between processors, I never compared them between desktop against laptops, because I was sure that desktops will win. Wrong.

My most powerful desktop is an AMD3+ socket FX8320, the second fastest in the family of 8 core processors built by AMD. The highest is FX8350. The absolute fastest is the power hungry FX9XXX but it is very expensive and consume too much power and is too hot.

Compare it to my second hand laptop, the Zbook 15, with i7-4800. The fastest is i7-4930 which this workstation is capable of. My Zbook is equipped with 32Gb of DDR3 1600 MHz RAM. My desktop was also equipped with 32Gb DDR3 RAM, at 1860 Mhz.

Look at the userbenchmark readings:

AMD FX-8320-RM 363 65,782 User benchmarks, average bench 51% Socket 942, 1 CPU, 4 cores, 8 threads Base clock 3.5 GHz, turbo 3.65 GHz (avg) Performing as expected (51st percentile)

Therefore the laptop is faster.

If I were to upgrade them to the highest: fx9590 vs i7-4910mx

Worse, desktop PCs CPUs consume more power, and higher frequency, and yet have much lower benchmark readings.
