sorry to hear they did not post.
There are other ebay vendor choices and I am glad to point you to the very competitively priced and reputable vendors that exist.
ON HEATSINKKS:
The cool server heatsink, (3 versions) needs to be the one with the full copper plate covering the CPU,
2 out 3 of the ones sold by them do not cover the whole cpu with the transfer plate.
Unfortunately all listed under the same sale items/same picture, but different products.
I ordered 12 to get 4 that were right, and returned , and then had to modify them anyhow.
ALL other air heatsinks are NOT enough, please review this thread to understand more and maybe sone beneficial details,
Get this version ONLY (picture)
the other versions have 30% less cooling fins, and 44% less coverage of the actual cpu heatsink plate
Lastly, the copper plate on the other two versions is 2mm thinner (not as thick)
visually if you go by pics, make sure the radiator is 120mm of fins wide and 120mm of fins long.
lastly the upper cover plate is black steel (not gray aluminum) has no writing on it and is secured by two Torx 15
FANS:
Use Phantek T-30 120
set the small switch in the back of each fan to the advanced mode
300Rpm to 3000rpm
use bios fan curve to manage fan speed
I can send you the optimized fan curve
these builds are very doable, work very well, set records and are very stable… when done right
