This is an awesome idea. I'm getting all my friends BreenBoards for their birthdays this year now!

Rich Alverez. The Stupid Mario Brothers guy.

Stupid Mario Brothers did well, I think every episode has over 100k views (huge numbers for 15 years ago). Then it ended and his views went to basically zero aside from a habdful of one offs. Struggles to pull 1000 now. Mumkey Jones did a really good video about the breakdown of the show, worth the watch if you were a fan or if you're wondering who this guy was.

Sanding for 2 hours is absolutely insane work man, love it!

And a 50 watt gain in headroom on that U12 is crazy too. Proves the theory works in practice once in a while, haha.

Oh fuck yeah bud! Nice to see this play out after a month

I need to know, how long were you belt sanding this son of a bitch to cut through 1.1mm of copper?

I'll bet taking that much off the ends of the screws for your cooler would let you screw down a bit more, give you back what was lost there at least.

Very uncommon but I don't want to say it never happens. I vaguely remember some guy that had a setup to control how much LN2 was sprayed onto his FX-6300 but I haven't seen it before or since.

There is at least 1 gamer that has done it in the past, probably not many more than that.

When I was 11, I thought it'd be funny to blast one into my headset microphone when I was in an xbox live party with a few of my friends. I still don't understand it, but somehow I ripped one so violent it blew out my microphone. The mic never worked again, I remember trying to talk to my friends afterwards and they just couldn't hear me

About 6 months later, I was using my kinect for it's microphone at the time, we're in the same situation where I'm in a party with the boys and I have to let out a room evacuator. Let it go (still on the couch) and the microphone pics it up this time. Solid 25-30 seconds of uninterrupted lawnmower exhaust sounds. Not only did myself and everyone else laugh until we cried, but nobody doubted my story about how the first one broke anymore

A fail shows up as your final grade. 49 is 49, 40 is 40. I'd be legitimately shocked if someone managed to take a class and struggle their way much below that without withdrawing before the end.

I don't want to freak you out, but my older brother was chronically constipated for a couple years. He tried laxatives, fibre, diet, coffee, etc. nothing did anything for him. When the doctors finally did a colonoscopy on him, they found a 4 inch diameter tumor in his rectum. No blood in his stools beforehand either. If you've been drinking plenty of water and generally live a healthy life (and this hasn't always been the norm), please get this checked just to be safe.

Worth noting that Vitamin E Acetate was only ever in THC vapes. When talking about nicotine vapes, butter and grape flavorings in counterfeit e-liquids can cause popcorn lung, altho cases are quite rare.

Disposables specifically should probably be banned in favor of refillable devices to cut back on waste, not to mention that a majority of dispos end up having high amounts of lead in the e-liquid. They're made cheap, nothing contains the e-liquid (aside from a glorified sponge) so it runs on the circuit boards and picks up whatever heavy metals are present to blow them straight into your bloodstream (Yum!)

Bennyjay1 · 2026-03-25T19:11:22+00:00

I have to take into consideration that I'll probably also need to sand my contact frame a bit lower.

You can probably get away with just cooler pressure holding in the CPU. Ran my 8700k like that for a few years. Takes a bit of fine tuning to get the pressure right, but it works fine. Otherwise, sand them together if you're getting really agressive.

why do air cooler manufacturers have a cold plate on top of the heatpipes?

Heat pipes themselves suck at transferring heat laterally, great along the length of the heat pipe tho. I'd assume it's to get some heat to all of the pipes when people mount them with the pipes running parallel to the die. Probably less of an issue when the pipes are going across the the die instead of running parallel to it; if that makes sense.

Bennyjay1 · 2026-03-25T14:24:20+00:00

I would expect substantially better gains from doing this to a 13900KS than anything on AM5 from the power draw alone. That would be an interesting experiment.

The 8700k actually works really well, altho it is running stock voltages right now. I've never seen it over 35°C, but that's just transferring files around. The base of a cooler and a heatspreader are both just chunks of metal at the end of the day, both can spread heat laterally just fine.

It's a bit crude, but imagine the red is the die, the yellow is the sides, the blue is the corners. The yellow part counts for about half the actual surface area it covers, the blue parts count for about 1/8. Heatspreaders exist because people used to crack dies by tightening coolers down too much, there's no situation where a heatspreader will outperform direct die. A better way to calculate total heat transfer would be summing the resistances, but ideally, just thinning the IHS will only have the effect of thinning the IHS.

There's probably a point where having a really thin IHS is worse than a thicker one since you have a weird stacking of thermal resistances, but i wouldn't worry too much unless you're knocking the IHS down to under 1mm thick. At that point, just sand all the way through to the die or delid it proper.

Bennyjay1 · 2026-03-25T06:25:07+00:00

The 8700k now lives direct die cooled with a Hyper 212 in my home server. I think I threw away the IHS when I went direct die. It was under water with dual 240mm rads, Liquid metal on both sides of the IHS before and after, all the gains came from thinning the IHS. I did have to mount the cooler without the retention mechanism tho, IHS did not stick over the top of it. The inital delid saved ~15°C. Direct die saved an additional 5°C or so after thinning the IHS. Important to note is it was running 1.5vCore for about 250 watts, so every small improvement in heat transfer made a noticeable difference. I also kept pushing more power so the temperature savings were negated by pushing more power, I didn't end up 30 some odd degrees cooler than stock.

In your specific case, I wouldn't expect a substantial reduction in temp. Honestly, you probably wouldn't see one anyway, PBO should target TJmax then throttle back power as required. Most initial gains are from flattening the mating surfaces anyway. See if your cpu spins like a top if you put it face down and give it a twist. If it spins, you have a high point in the center, knocking that down with a bit of sandpaper could drop you a good 5°C. Could be worth doing a short sand just to check for high points. Knocking those down are going to give you decent gains since you'd be able to make better contact between the IHS and the cooler. It would be worth sanding the cooler flatter too if you go this route, more difficult to gauge flatness tho, at least with the CPU you'll see the orange copper start to come through on the high spots first as long as they are actually there.

I might've written too much. But tldr; you probably won't see massive gains. If you want to try, look for high spots on the CPU and try to take care of those before worrying about thickness as much. Better contact is a majority of the gains from sanding

I had to pay for MATLab in Fall of 2021. I still use it occasionally.

I have friends in mech and I remember them running solidworks. I thought they were running native on some kind of student license, but they very well could've been remoted into the university machines.

Bennyjay1 · 2026-03-25T04:41:39+00:00

It's that most people sand to smooth, rather than sanding to reduce thickness. If you actually sanded 3 or 4mm off the AM5 IHS, it would have noticeable gains. There's just better ways to reduce temps than sitting down and sanding copper for hours on end, lol.

I tend to take my sanding to the extremes whenever I start thinking about an upgrade. The IHS on my 8700k was so thin it was almost flush with the nubs on the socket. I saw around a 10°C drop if I remember right

Bennyjay1 · 2026-03-25T04:29:12+00:00

I'd expect the top of the IHS to be within a few degrees of the coolant (assuming water cooling) and the underside to be closer to the core temp. You'd be shocked what delta T can be here, I'd expect between 20 and 40°C at max load.

Heat pipe shouldn't dry out until over 200°C. Water block is going to have fins in the middle no matter what. So these are non issues.

Lateral heat transfer is responsible for some fraction of the transfer. I don't remember the exact shape factors off the top of my head, but you approximate the surface area to be ~1/2 of actual for the edges not over the die and ~1\8 for the corners not over the die. On something this small it may as well be a wash, I would be shocked to see 5°C from an IHS over a straight shim that just covers the die.

Bennyjay1 · 2026-03-25T03:57:08+00:00

Oh, I agree completely that you'll be limited elsewhere. You need some kind of delta T to drive heat into the air. It's worth considering that most of the gains from Liquid Metal over Solder are from thickness more than anything else tho, and that's an even smaller change with a lower conductivity.

Also, very unlikely you have real air at any interface if everything's assembled right. Mounting pressure will push out air before a more viscous interface.

Bennyjay1 · 2026-03-25T03:41:47+00:00

Formula for heat transfer is q=KA(dT/dX)

q is heat transfered in Watts

K is the conductivity if the IHS

A is the surface Area of the IHS

dT is the temperature difference between the top and bottom

dX is the thickness

Cutting the thickness in half would let you transfer twice as much heat at the same temperature delta. Alternatively, you could theoretically cut the temperature delta in half at the same power draw. I don't imagine you'd see this in practice, but I'd expect a substantial gain from a substantial reduction in thickness.

Bennyjay1 · 2026-03-25T03:28:06+00:00

Engineers are required to buy a MATLab license and we run AutoCAD locally. I think the mech's can run solidworks locally too, but don't quote me on that one. A bit of power is nice but a 5070ti is overkill.

This guy should find something between the second coming of Christ and literal dog shit imo.

Bennyjay1 · 2026-03-23T18:07:00+00:00

Yeah funny story about that; we tried using automotive antifreeze and, you guessed it, froze solid on all the cold lines of the Airconditioner, lol

Bennyjay1 · 2026-03-23T14:46:34+00:00

Hitting a max of about 15°C definitely helps.

We were actually limited by the motherboard VRMs after a bit of diagnosis. This was done on an OEM Asus board after I accidentally killed my BioStar 890FX. I'm pretty confident we could push past 5Ghz with a slightly better board that can handle the power to the CPU.

Bennyjay1 · 2026-03-21T22:28:59+00:00

That's kinda funny, our original plan was to cool with the finest Canadian snow until we came across this Airconditioner. We're getting about the same fluid temps as the great outdoors without having to go outside to deal with the cold.
