I know what copper is, I wanted to know what is inside them, if anything.
I thought you said the mobo and psu won't supply enough watts for them.
I saw a YouTube video on it and it does cool more and is quieter but it is only 2000 rpm and the stock intel one spins much faster.
There is nothing inside the copper pipe of the CPU heat sink. The copper pipe just acts as a conductor of heat from the heat sink to the cooling fins.
I ordered this cooler to fit to my 8930. Did you mean M3 x 80mm or M3 x 8mm?
Is it the screws to fit the black plastic guides or the screws from the fan to them? If it's the latter, then it must surely be 80mm?
EDIT: It's okay, I get what they are for now. Fixing the black plastic guides to the motherboard.
Have you seen the unit Dell makes for the 8930 that drops the temps 18* F ?
First off all, thank you for your detailed post and solution aleg123.
I too have now implemented your solution. Too the others that are also looking to use this solution.
I am running BIOS version 1.0.11. With the stock cooler I got an average of 75 degrees Celsius in prime 95 (small FFTs) at a package power of 65 W constant, all cores throttled at 3.2 GHz after a while.
With the Arctic cooler Freezer 11 LP I am getting the same temps in prime 95 with the same settings.
I have not tested gaming yet, but think the temps might be lower than before in games as it is not as intensive as prime 95.
The cooler does sound more quiet too me than that of the stock cooler on full load. And personally it just sounds better to me even when it is spinning at full load, i.e. the fan bearing/mechanical sound is not as harsh as it was with the stock cooler.
My system is also the DELL XPS 8930 i7 8700 (non-k) version.
Maybe it's just not spinning those high oem rpms, also the latest bios update is 1.0.12
