As you can see in the pictures, my Laptop also run a I7 it's something 2012.. is on 2.2GHZ
First Picture shows Windows Taskmanager which is on IDLE look at the differnt Value like = Percentage, Heat Power etc
The other pictures are on Simulating Multisimm 14.
One Important thing is: Your CPU runs on 3.3Volts and not +- 42 or just even 36.
Then also INTEL CPUs, all of them having Intel Speed Step which always is on. If you switch it off *usually in the BIOS* then CPU will run at it's lowest Frequency. Here a few Pictures take from my Laptop just a few minutes ago
It's a MAC BOOK PRO 2012 , running Windows 10 Enterprise
Now again look at the FAN SPEED temps etc
If this would be a gaming computer this would be disaterous for it.
And a CLASS A is evern worse, my single end goes from 25 Degrees up tp 59 within 2 Minutes and then the FAN KICKS in, but it just turns enough to keep it below 70 Degrees, even surrounding air is 25 / 30 degrees.
So my Class A runs the less hot one runs on 37 Volts with 3.7 ampere IDLE
37x37=136 Watts per Channel delivering only 18 watts RMS into 8 Ohm the rest is HEAT
The Hot one is 42X 5.6 = 235 Watts and delivering maximum 26 Watts RMS into 8 Ohm the rest is heat.
but the sound is unsurpassed if we are talking about Transistors.
Now, just to burn less heat for nothing I'm testing a Cirquit which I can choose the POWER OUTPUT to the need of the Listener.. I have this for manual switching but I would like to have it Automatic, that the AMPLIFIER decides by itself which RE is should use and of course switches them automatically. Three Variant are Valid,:
RE 15Ohm for about 5 Watts output,
RE10 OHM for about 12.5 / 15W output depending on RAIL VOLTAGE and then the hot version
RE 7.5 Ohms output for 20+Watts Output..
If you take non FAN HEAT SINKS this will be quite large Pieces..
Hope this helps
here a pic of the AMP with active cooling heat sinks from MAC Computer G5
There are no dumb questions, there are only dumb answers.Accepting criticism is not for everyone..
Your criticism helps me to improve
