I knew there was a way to do that as I have done it before, just didn't have the time earlier and I'm sure I did it similar but a different way.

Mork, watch the evidence video it will show you how he did everything. But it was actually his recordings of his record attempts that were his downfall.

So I did the post on a nice custom PC and there was some discussion on temperatures. I just bumped into this from Linus Tech Tips, now that's what you call ultimate CPU cooling.

It's not even phase change never mind LN2.

This whole Delidding thing is, only a thing, 'cos of the horrendous paste Intel uses on it's chips.
Hell it even cracks when going well into minuses under LN2 cooling. at least AMD solders it's high end chips.

It was meant to be more of a light hearted post, as you would have to be insane to go that far just to cool down your CPU.

OmegaKnight · Post by **OmegaKnight** » Mon, 16. Apr 18, 05:08

Well you say that but...
Delidding your CPU then direct die cooling IS pretty extreme.
Given the risk of damage to the PCB with bending and losing contact with the socket or worse cracking the die.

Add to that Liquid metal, which contains Gallium(Ga), Gallium does not react well with Tin(Sn) (well it does react, that's the problem). Tin being a constituent of solder.
A few people, that had volt modded their graphics cards, found this out when the shunts, that they had shorted out with a liberal amount of liquid metal, fell off the cards.

So unless you want to paint of the surrounding components with a healthy coat of nail varnish,
Not something I'd want in my rig, given the small gains and high risks.
And I'll reiterate, Delidding wouldn't give you any decent gains if Intel hadn't cheaped out on manufacture.

Phase cooling isn't insane, it just never really took off because of the noise.
People want quiet computers and putting the gubbins from the back of your fridge in the bottom of your PC case doesn't make for a quiet system.

lol you tube
Running on Empty Food Review

Apparently he started doing this when he was around 10 yr old .

He also does a music and some lite answer questions over the HF freq range .

Why did they start adding heat spreaders to CPUs anyway? I remember a decade or so ago where all CPUs were basically naked cores with the heatsink attached directly to them...

Why are they on RAM chips? the ones I bought for my latest PC look like they've got go-faster stripes on them. I've not had that before, which shows how often I update my computers. (Spend a lot, built it to last, that's my thing). The Corsair one I bought have Johny Bravo hairstyles going on.

Some even have LEDS for heavens sake. That I sort of get, it's for people with an urge to have lit up rigs. But don't want it, not even the tiniest bit which restricts my choice.

Aren't CPU manufactures missing a trick here, they couldn't they basically make a version which was all fancy and super heat optimised, called it the Ultra Xtreme L33t version and charge an extra $200 for it.

Do you mean the likes of X-Series Extreme Edition https://ark.intel.com/products/series/1 ... Processors
which might lack the better heat optimization, but at least offer the higher price tag?

felter · Post by **felter** » Tue, 17. Apr 18, 00:19

WOW, the i9-7980XE Extreme Edition, I would love one but they sell for £1500+, right now I could just do with the £1500. Plus another £200+ for a mother board and then another £200+ for some DDR4 memory. I wish I was rich.

Probably bending/ cracking with the PCB/substrate becoming thinner and the pins increasing in number and becoming smaller. quiet easy to bend a modern CPU if you don't evenly fasten it down or over tighten it.

pjknibbs wrote:I remember a decade or so ago where all CPUs were basically naked cores with the heatsink attached directly to them...

Well all the Pentium chips have an IHS on so that's 25 years back

The 486 style chips are sort of upside down to today's Intel chips the heat spreader was on the bottom with the pins see here
So that's even further back.
You'd have better luck with AMD, their K8 series (Athlon 64) was the first to have an IHS, I think, and that was 2003 everything before that had an exposed die.

Agree

Hahahaha

I think, it's 8 tenths marketing and 2 tenths arse covering, for those really poor airflow cases.
Mind you they may help when you dump a load of volts into them to tighten up timings and/or increase the hertz
but ram overclocking is a whole other conversation.

Rather the result of a Intel's monopoly and getting complacent, "lets save some money by using old toothpaste as TIM", another reason why Ryzen is such a good thing.

Hackers once stole a casino's high-roller database through a thermometer in the lobby fish tank

Finally someone is attempting to get a grip on IoT! Maybe... Probably. Or, maybe just for show?

I have one "Internet of Things" device and I don't let it "internet." I also don't let it "network." It's probably pretty ticked-off about that.

LOL, that was awesome. Tks! (I especially love the TMobile Austrailia awesome great security thread.. I'm surprised their entire Aussie operation isn't one huge dumpster fire right now.)

LOL... "Electron Security." That's a pretty intense protocol.

Gotta go buy some line-scrubbers, now, just so my toaster doesn't leak.

What's new? Power and natural gas companies read your meter over modulated AC though the power lines. Quite a few other applications feed signals though the power lines. The means are almost built into power grids and utility companies keep their own computers isolated from it just for that reason. However how are hackers going to isolate to a single computer? They couldn't. So most likely it be to take out every system that was vulnerable.

This story is pretty cool. I hope they find it and recharge the battery and someone doesn't pinch it.
