- I found an unusually damaged IHS. Does anyone know how this could have happened?
That's not damaged. That happens in the molding process of the IHS. Sometimes the molds don't get cleaned properly and they end up textured on the sides. Doesn't affect the cooling at all. It's just cosmetic "damage".ID: h9aljnw
Yup, my former 2700X has the same roughness on sides.ID: h9bukvh
That's pretty interesting. Thanks for the insight. My guess was corrosion.ID: h9b0wtl
Molding? I'm sure they just stamp the metal pieces out of metal sheets, then grind down the top to be smooth. That being said, simply apply thermal grease, tighten it down, maybe do a few menchmarks, shut it down and remove the cooler. If the grease have spread out evenly, no worries. Clean off and reapply.
If there is a visible difference where that mark is, it's been REALLY abused and you should be cautious going forward.ID: h9byp2h
I would say the metal is pre finished then punched, which explains the stress marks in the corners still being present. This punch was likely worn and maybe lacking lubrication at the time. As long as the top is flat it doesn't really matter. Looks pretty rough though.ID: h9bkjeo

yes, but the part of the tool used to make the shape is still called 'a mold' in the industry jargon. (and you know how readily English uses every possible word as verb :D)ID: h9dmmoi
I'd assume it's a mold because there's no corner cuts at the rounded corners to allow for folding the sides flush. At least the last time I looked at an AMD IHS. It could be a hot press where it just heats the metal then presses out the shape, stamp/cut, and sand to smooth the top.ID: h9b5d2l
Are menchmarks benchmarks made by Jewish programmers? Or Jewish tattoos?ID: h9c175s
They still use a mold of sorts. It's not abnormal.ID: h9emovo
There is a video that goes over how Intel specific cpu's are made and the machine is insanely huge. Though after watching they don't show you if they stamp the ihs or not. I would suspect that it's still using a hot press to do this either way of they are stamping it would still be molten bc they'd change the metal by stressing it when it's cold. What you're seeing is left overs left in the mold even though the machine is supposed to clean the mold as it lifts off the CPU IHS blanks. Some of the molten metal gets stuck to the mold why I'm not sure as they use oil or some type of viscous liquid between the mold and the dies themselves. It's very interesting how they are made.ID: h9ab3uv
Huh. I don't imagine it affects performance- it's just a block of metal, and smooth on the surface, so good contact with the cooler. But just found it unusual. Thanks for clearing it up.
That's normal, my Ryzen 7 1700X also had those lighter edges.ID: h9admyc
Huh. I guess this is common in first gen Ryzen? Another commenter posted this is due to issues with the mold.ID: h9b6yuq
I sold my 1600 a long time ago, wish I could go back in time to seeID: h9bdago
My old 2600 had that but only on 1 side afaik.ID: h9bn8oi
This is common with every AMD IHS. I have a couple laying around here Athlon 64 and Athlon II, they all look the same. IHS pic
The easiest way to tell its a defect and not damage? The IHS is nickel plated copper. If that part had been damaged like that the copper would be showing through.
Those marks are almost certainly due to the punch tool used during manufacturing being worn. Shouldn't be a problem as long as the IHS is still flat, although a worn punch can definitely cause a bent finish.
Fyi it's not .ID: h9bdgj7
Other commenters expalined this is how they came from the factory- which is what I was asking.ID: h9bdmn3
I too have a amd processor and not all sides and perfectly sealed in thr sense not like bad job just thr other parts isnt polished or something like that
I was helping someone fix their PC, and what most likely happened is that the motherboard took the GPU and CPU with it after the PCIe slot got bent due to a large newtonian shock to the system.
After we were done, I got to take the old parts back, and this is what the Ryzen 3 1200 looked like. All the pins are straight, and presumably the part worked fine before the incident.
Is this due to delidding? I've never seen a delidded CPU yet, so I was thinking maybe that was it.ID: h9aruwk
Delidding completetly removes the IHS, so no - unless someone were to remove it and then reapply it.ID: h9av8up
From what I understand, delidding is used to replace the TIM between the CPU and IHS.
I've seen this on a couple ryzen CPUs. Some are rough there and some are not. The first time i saw it i though the CPU had been de-lidded at some point.
hand palm oils do this to my macbook aluminum case
De-lidding attempt gone wrong lmao
Wonderring what happened to this boy
Looks like a manufacturing flaw.
No you should class action lawsuit AMD at this point for providing such raffled up IHS's.
No these things are soldered straight onto the die. The side has zero to none effect other then providing a solid base to prevent cores from being chrused. Nothing to worry off really.
Shipping always manages to overdo itself. DamnID: h9aeudw
XD. I will add the cooler in that build was not clipped on, but glued on. It's all good and clean now, but... I'm not surprised the GPU did yeet out of the socket with what was described to me as a good kick.
