MD’s Ryzen 7000 processors have come below hearth 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 can make sure the chips run a good bit cooler. However, that is positively not one thing we advocate the typical person ought to attempt (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 device. Yes, the answer to the thick IHS for this Ryzen era – we’ll talk about why it’s beefier afterward – is just to make it thinner by grinding it down.
Obviously this isn’t one thing the typical PC proprietor desires to do, however extra hardcore varieties could contemplate exploring this avenue – and a few have already got finished within the case of JayzTwoCents with the usage of knowledgeable overclocker Der8auer’s grinding device – as noticed on Twitter by Andreas Schilling (by way of Tom’s Hardware (opens in new tab)).
With slightly assist of @der8auer and his Ryzen 7000 grinding device, @JayzTwoCents simply confirmed which you could cut 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 have 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 referred to as ‘delidding’, the place the CPU has the IHS really eliminated, which can lead to even larger 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 numerous further work in becoming a cooling answer to a delidded (very in a different way sized) chip – however granted, in each instances, you’re voiding your guarantee. And except you actually know what you’re doing, you’re operating the danger of ruining the CPU as you may think in terms of drastic motion like pulling it aside or grinding bits down. Which is why we actually wouldn’t advocate this to anybody however knowledgeable lovers (who can afford the fee if issues go mistaken, for that matter).
The complete 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 with the intention to preserve compatibility with new Ryzen 7000 CPUs by way of present (AM4 platform) coolers – so of us don’t have to purchase a brand new cooling answer – as the brand new socket is flatter, which means the chip sits slightly decrease (so the thicker IHS makes up for that distinction). But that thickness of 1mm further than typical 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 carry the IHS again to about its earlier pre-Ryzen 7000 measurement, having the processor run at extra like 85C, a degree 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 have been.
If you’re fearful about your Zen 4 temps – which can, after all, range from case to case anyway – moderately than go this route, it’s a significantly better and extra possible thought to take a look at various options reminiscent of utilizing Eco mode settings (in AMD’s Ryzen Master software program) to rein in that warmth. (Or undervolting is another choice, maybe).
