Question 1

How much does it go beyond the advertised 65W at full load? What is the real TDP?

Accepted Answer

On default settings it goes to a little over 100 watts when stress testing in Prime95.

Question 2

Does this come with a cooler?

Accepted Answer

Hello Bret Anderson,

Thank you for contacting us in regards to your question.

Yes it comes with a cooler and heatsink.

Thank you and have a nice day!

Question 3

Is there a way to downclock this to say 2.5 ghz to lower the tdp?

Accepted Answer

You can set the frequency lower and potentially limit the wattage, but this thing is power hungry and runs quite hot. You'd be better off getting a lower powered Processor instead of trying to downclock this one. I personally limit the maximum time it can go over TDP to 1 second (down from 20) so it rarely uses more than 64 watts @4.6ghz

Question 4

What is the max 8-core clock frequency during turbo boost?

Accepted Answer

Hello,

This is not something that can be provided since turbo clocks are your best case scenario if your CPU can handle that clock speed under ideal conditions.  This would mean that you would have to test the CPU yourself under your conditions to determine what that turbo clock might be, you should also take "silicon lottery" into consideration as your specific unit might not be able to reach the same clock speed as someone else's unit (of the same CPU), even if operating within the same conditions.

You can check online to see other people's results so you can see what to realistically expect should you decide to get this CPU, hope this helps!

Question 5

Will the stock cooler be enough to cool the processor in intense cpu loads without thermal throttling? I don't want to have to buy a separate cooler.

Accepted Answer

Hello,

Thank you for contacting us in regards to your question.

Sadly, for this type CPU requires a really good CPU cooler or water cooler to prevent it from overheating.

Thank you,

Question 6

Intel  use solder TIM on  their 9th gen cpus i9 9900?

Accepted Answer

Hello,

You will need to contact Intel about that I'm afraid since that information is normally not listed on the page, sorry about that!
