Putting paste on that looks fun...

Guess we will have to use pads.

I see more than few people here and there talking about prossible problems regarding applying and removing thermal paste on new Ryzen 7000 series but honestly there's nothing to worry about folks, just use some type of sticky-tape, make a square surrounding IHS covering all 8 "IHS legs" (and SMDs between them) and you're good to go. Two minute job. Here I did it with kapton tape (so it can be clearly visible) using CPU pic from Guru3D article but using any tape will be just fine:

Why is everyone panicking, just use pads.

Why worry about *cleaning off* the paste that flows over the edges and onto the capacitors? As long as your thermal paste is not conductive. If you doing a second application years down the line, you only need to clean the IHS where it makes direct contact with the cold plate. The things people worry about.... 🙄

So, They actually do look like that. Nice but not practical, I could always fill in the gaps with solder or something. Hmm

Honestly don't know whats all the fuss about, folks don't know how to improvise or what?

Netherwind:

Good idea but when one wants to change paste after several months it will be tough to clean like someone said as the paste will be spread out in all corners.

Just stick some cotton (lets say cotton pulled from cotton swabs) between IHS "legs" to cover/protect SMDs between IHS legs and then clean old thermal paste from IHS without fear that thermal paste is gonna escape and stick between SMDs around IHS. I bet experienced folks here who do electronic repair on daily basis can suggest at least 10 more ways to do this and protect the area between IHS legs with or without SMDs: - to cut and insert small pieces of thermal pads between IHS - small sponge pieces - small pieces of make up remover pads - to roll small pepper seed sized pieces od toilet paper... One just need to insert something soft and easy-to-remove thingy between IHS legs before cleaning the old thermal paste. Before applying new thermal paste make a square around IHS with sticky-tape, like on that one picture I've made in my previous post here, and you're good to go, apply new thermal paste the way you like.

I wonder if the latching mechanism will be strong enough to apply even contact pressure across the IHS

Aren't most pastes not electrically conductive? I don't see the problem here. I wouldn't be surprised if those SIMDs are coated in something anyway.

I think i m doing something like that, move from 2700x to 5800x, search a replacement for the 3200cl14 that will actually improve something, and then just think to move forward from the 1080ti. Like those: https://www.gskill.com/product/165/326/1620976207/F4-4000C14D-32GTZN

Thats what i was looking for but couldn't find any c14 at the time so i got 32gig (4x8)Royals instead and they were not cheap....£440 not cheap....only problem is the b550m mortar board i changed to does not support board 4 dims at 4000 but 16gig at 4000cl14 is enough.

Pretty sure I recall seeing several of these in the Engineering spaces aboard the USCSS Nostromo.

Horus-Anhur:

Those cuts have to be machined. So that material is just waste and it has to be sent back to be smelt again. The machining costs more than whatever could be saved with material saving. My thought is that AMD needed those cuts to give room to those capacitors.

I don't know for certain, but I'd be quite surprised if it isn't simply a stamped part, rather than something machined. Metal stampings can be made rather inexpensively, and are more than sufficiently capable of maintaining precise dimensional requirements. I'd bet an inflation-tainted dollar that pretty much all CPU heat-spreaders are simple stampings. And, I'll bet an additional dollar that someone will be along shortly to prove me wrong. And, that's fine. The spice must flow...

Wrong you get the 3ml syringe and start squeezing in the CPUs general direction ! OBVIOUSLY! ;P

The cutouts are there for space needed by those big capacitors and to provide some cooling for them. As for the paste entering there - a lot of very good thermal pastes nowadays are non conductive so no issues here. I am a little worried about the reduction of the heat distributor surface because of these cutouts but we'll see... Also the 7700X is said to be delayed because of BIOS and memory issues.

The IHS is also roughly 3.5MM thick, there was a picture of a cross section some weeks ago. I wonder what that will do for the heat. It has to be that thick as well, because otherwise the IHS wouldn't protrude the mounting system, as the Z-height is so low.

Guys you know the solution to this? thermal grizzly carbonaut 😀

That pad alone is the price of a half decent cooler or half price of a decent one.it's reusable though so it's acctually not a bad idea.

Possible dumb question... Can you get the tape off once the heasink is in place? I think my waterblock is big enough to cover quite a bit of the tape.

Looking at the CPU pic on Guru3D article here... Think that's quite possible, to remove the tape on these Ryzen 7000 CPUs after heatsink is in place because there is a visible curvature of all 8 IHS "legs", "legs" cuvature to the outer side. But guess one has to use strong and thin quallity tape, like that one kapton tape I've used.

Not sure what's the deal with thermal paste application. I mean I don't see why the pea technique would not work while using non conductive thermal paste which is what most people use. Removing the paste and cleaning the cpu could be fun though but it's always "fun" anyway tbh.

I accutally prefer lga to pga in the long run, easy to bend the pins if the paste gets hard and the cooler sticks. it was easy with less of them, now there's +1700 pins so better to use lga.

With Arctic's MX-5, you don't need the paste to get hard. I've seen epoxy with less holding power than fresh MX-5.....

There's still plenty of silver and copper based thermal pastes on the market....

I simply can`t understand why AMD made some cutouts in the sides of the heatspreader. Applying thermal paste is going to be much harder than it should and i can already see some people returning their CPUs because of this decision...

probably for structural reasons, if they had covered the whole thing, it would be a bigger package, if they reduced the size of the heat spreader ,it would increase the risk of the pcb flexing. at least thats what my intuition is telling me. I'm more surprise they didn't put some more epoxy over the simd components.
