We can't benchmark Threadripper yet, but we can cool it

It has been a long time since lapping was a requirement to get the best cooling for your new processor, however it might be making a comeback.  Threadripper is endowed with a larger heatsink than your average CPU and to help you accommodate that the chip contains an Asetek mounting bracket which is compatible with most AiO coolers.  The bracket and size of the heatspreader do seem to exacerbate any curvature of the coldplate however, the Asetek AiO which [H]ard|OCP tested needed to be lapped for a proper mating.

Since they had some difficulty with AiO coolers, [H] decided to configure their own watercooler for Threadripper.  They grabbed an old Koolance water block they had handy and with a bit of time and a $10 trip to a hardware store they ended up with a much better solution.  Take peek at the process, especially if you happen to have parts lying around that you want to put back to use.

"What do you do when you don't have the proper parts that you need to water cool your new thread ripper? Make you own with trash you find around the house. Maybe even repurpose and old water block that is in your closet."

Are you still lapping your heatsinks?

Back in the ancient past of aircooling, when heatsinks did not weigh a kilogram and 120mm fans were a novelty item and not the standard many enthusiasts practiced the art of lapping.  With a water tray and automotive grade sandpaper of increasingly fine grit you could not only flatten the base of the heatsink, something that was all too necessary for some models, you could also acheive a mirror finish which helped your heat paste spread evenly.  Today you do not hear much talk of lapping either heatsinks nor the integrated heatspreader on CPUs and SPCR decided to test if it remains a good practice.  Check out the difference a proper lapping job still makes, though keep in mind lapping the IHS on your CPU will void the warranty and could weaken its structure.

"Lapping the CPU in a heatsink test platform is probably a controversial move that's bound to provoke reactions. Funny thing is, it was done a year ago, and photos of the CPU showing the copper top exposed by the lapping have been featured in many of our reviews. Yet, not a single comment. This article goes through the problems, investigations and explorations that led us to lap our Core i7-965 Extreme test CPU, and analyzes the results and implications."
