AMD’s Ryzen 7000 processors have come below fireplace for the design of their built-in warmth spreader (IHS), and the way it doesn’t assist thermals – however there’s a method round this apparently, one that may make sure the chips run a good bit cooler. However, that is undoubtedly not one thing we advocate the common consumer ought to strive (not that they’ll be geared up to anyway).
Why? Well, as a result of it entails taking a shiny new Zen 4 processor and exposing it to a grinding instrument. Yes, the answer to the thick IHS for this Ryzen era – we’ll focus on why it’s beefier afterward – is solely to make it thinner by grinding it down.
Obviously this isn’t one thing the common PC proprietor needs to do, however extra hardcore sorts might think about exploring this avenue – and a few have already got accomplished within the case of JayzTwoCents with using skilled overclocker Der8auer’s grinding instrument – as noticed on Twitter by Andreas Schilling (by way of Tom’s Hardware (opens in new tab)).
With a bit of assist of @der8auer and his Ryzen 7000 grinding instrument, @JayzTwoCents simply confirmed you could scale back the temperatures of a Ryzen 9 7950X by as much as 10 °C by grinding off the heatspreader by 0.8 mm.

The results of shaving down the IHS of a Ryzen 9 7950X CPU by 0.8mm proved to be a discount in temperatures from 94-95C, right down to 85-88C, a fairly substantial drop (these had been the temps operating at 5.1GHz throughout all-cores for the CPU).
Analysis: The lesser of two evils? Well, not precisely
Essentially, that is an alternative choice to one other dangerous process often known as ‘delidding’, the place the CPU has the IHS truly eliminated, which can lead to even greater temperature drops. (Der8auer demonstrated an enormous 20C discount when delidding a 7900X beforehand, though that was utilizing a particular liquid steel thermal grease which is the overclocker’s personal customized concoction).
Grinding down the IHS represents a considerably much less dangerous path – and fewer fiddly, too, as there’s a number of additional work in becoming a cooling answer to a delidded (very in another way sized) chip – however granted, in each instances, you might be voiding your guarantee. And except you actually know what you’re doing, you’re operating the chance of ruining the CPU as you may think relating to drastic motion like pulling it aside or grinding bits down. Which is why we actually wouldn’t advocate this to anybody however skilled lovers (who can afford the fee if issues go mistaken, for that matter).
The entire backdrop to that is that AMD has used a thicker design for the IHS with Zen 4 chips on the AM5 platform (with a brand new processor socket). This is so as to maintain compatibility with new Ryzen 7000 CPUs by way of present (AM4 platform) coolers – so people don’t have to purchase a brand new cooling answer – as the brand new socket is flatter, which means the chip sits a bit of decrease (so the thicker IHS makes up for that distinction). But that thickness of 1mm additional than common is considerably counterproductive for good thermals.
Now, AMD reckons it’s high quality for the Ryzen 9 7950X to tick alongside at temps like 95C, however some lovers beg to vary, therefore the controversy. And therefore shaving off 0.8mm to deliver the IHS again to about its earlier pre-Ryzen 7000 dimension, having the processor run at extra like 85C, a stage homeowners are happier about.
As an apart, don’t overlook the IHS is there to supply safety for the CPU, and with delidding that represents an additional danger by way of leaving the die uncovered – whereas grinding it down nonetheless leaves a protecting lid on the chip, because it had been.
If you’re nervous about your Zen 4 temps – which can, after all, differ from case to case anyway – reasonably than go this route, it’s a significantly better and extra possible concept to have a look at different options comparable to utilizing Eco mode settings (in AMD’s Ryzen Master software program) to rein in that warmth. (Or undervolting is another choice, maybe).
