PS3 Keeping temps low in a CECHGxx

[Naked_Snake1995]

That looked easy.
So I should remove the IHS in that same way, clean the 4 VRAMS and the chip in the center and apply paste in all of them?
Do you have a good tutorial for applying the paste and putting all back together? Do I need to reglue anything else or just put the IHs freely and screw over it. Do you think CELL needs a delid too?

I just dont delid the CELL because the risk its too high,even for more experienced users, you can scratch the CPU Mask, and if you do,you can kiss your PS3 goodbye. I did once back in my reckless youth days, almost 9 years ago, delided a CECHG04 40Gb with a knife "youth stupidity" @Cypher_CG89, likes my Knife Methods, ever since then CELL Deliding has been out of the question for me

Thats what you effing think mate.....

A simple L shaped bit of 3 - 4mm thick metal on top of cardboard padding on the MB is all that is really needed lol... max leverage and a fulcrum point is always better, thats less force needed and this way you cannot scratch a thing....and NO KNIVES are needed... at least on the RSX. CELL is more tricky but the priciple is the same..... applying mechanical knowlege and methods to other things works wonders mate... ...simples....

In the RSX the VRAMS (in the corners) and the DIE (in the center) have different heights... lets say there is a diffrence of heights in between them of 0,5 milimeters or so
So you can do 2 things

The "pro" way is to use standard thermal paste in the DIE, and thermal silicone in the VRAM chips
There are some brands that sells that "thermal silicones" in high quality (for electronic devices), it becomes like rubber when dry

The cheapest/easy way is to drop a lot of standard thermal paste to fill the gap in the VRAMs... this works and is fine because the VRAMs doesnt generates much heat by themselfs

And to "stick" back the IHS in place.... there is people that doesnt sticks it... it doesnt have much importance if you assemble the PS3 parts well because is kept in place by pressure, but it could be a pita, because is tricky and could happen that something moves when you are asembling the PS3 "auuuuch, back to step one"

So... personally i think is better to stick the IHS by creating 4 "columns" at the sides
And by using thermal silicones typical from cars, the gray is to seal engine blocks, and the orange is to seal interiors from noises
Are easy to find, are cheap, and both resists over 100ºC without problems

Look, this is what i mean about how to stick the IHS back with silicone (you can use any silicone, the only requirement is it needs to resists a minimal of 100ºC)

The blue dots are "columns" of silicone

With the CELL you can do the same to stick the IHS back... the reason why to do it this way is because if at some point you need to remove the IHS's again (to replace thermal pastes under them)... is going to be very easy to "cut" this silicone columns to remove them

Personnaly, I use copper based gasket silicon sealant to stick back the RSX and Cell IHS. Need to remove any residual resin on top rsx ram to ensure a good contact on the die.

I never had it in my hands, so is hard to get an idea of how much flexibility it have
And are you dropping it on top of VRAMs ?

One of the things i hate is when this thermal components becomes solid as a rock (so is imposible to unstick them after they gets dry)
The fact this one you are suggesting is made by loctite scares me a bit

I was thinking something like this would be best as the copper content would ensure good thermal conductivity as well. But was thinking that am nuts for even thinking of use things for cars on my PS3s, got some of this in the garage somewhere and other sealants like this.

Have a photo of that product ?, im googling it and i guess it comes in a tube made by loctite ?

This won't become hard as a rock with it being gasket sealent as it needs to expand and contract with the heat of the engine or the seal would be broken if it didn't. They are super durable.

 

[sandungas]

Ok, i got it, so that "copper based gasket silicon sealant" made by loctite is pretty much what i was saying when i suggested to use the gray silicone to seal engines

The difference is the gray one is cheap and it comes in big tubes... and the one made by loctite have copper particles + his chemical formula, etc...
But at the end of the day both are silicones and are used for the same purpose... so i guess the flexibility is going to be pretty much the same

The good thing is you can "cut" them with a plastic (e.g. a credit card) if at some point in the future you need to remove it

I would say to people to stay away from the clear stuff for gasket seals, its nasty. I did a service on a car about 2 month ago and done the sump seal as well and it used the clear stuff and it took me 1.1/2 hours just to get it off the sump and the bottom on the the crank casing.

So you can imgine what it would do to your PS3 if some used it thinking its the same as the grey, but also some of the grey stuff is nasty as well, stay away from the super cheap stuff as it does the same as the clear and will never come off your PS3 as you cannot do what is needed to get it off properly as it would destroy your PS3.

I meant this ones that comes in big tubes
There are many brands, im just posting a link to the first that appeared in google
https://www.amazon.co.uk/Temperature-Silicone-Sealant-Quality-Cartridge/dp/B071ZLSLVJ
You know, in a garage is needed to have 5 or 10 bottles of it because is used very frequently, sometimes even several times every day
Kind of industrial quality to be used in bulk
This silicone usually have gray color because the metals are gray

There is another pretty cool used in cars, is orange color, and used to isolate the cabinet (to remove noises and vibrations), this one is a lot more flexible, is more "gummy" on purpose, is not intended to transfer the heat but both can hold up to 300ºC or so

The other suggested by littlebalup is a bit the same than the gray one i mentioned... but in very high quality. A lot more expensive than the gray one

Yes one dot on each ram for the rsx and one dot at each corner for the cell. It stays soft and is easy to remove if needed. It's mainly to maintain the IHS in place during reassembly.

 

[umart666]

i don't get why you would want to seal the IHS again?it's inevitable that any paste will need to be changed eventually,why would you create additional risk and obstacles again.ps3 are pretty stationary,it's not like it would move anywhere.

 

[NewFile]

I did it. I created a stracht in the chip too but it booted fine.
Right now temps are 55 CPU 67-70 RSX at 8% fan speed.
What have I done wrong?
Note, that I could not clean the glue on the 4 VRAM sticks. Those were hard as hell.

I applied paste in the 4 VRAMs. Spread the paste in the main chip and also put a small dot under the IHS. But the IHS freely and then assembled it(after spreading paste in CELL and RSX)
Did I use too much paste?
I suppose I am lucky that the scratch did nlt cause any issues. Is that a default RSX line? It was like a perfect line/sctrach close to one of the borders.

 

[umart666]

without the pic we can't know for sure.from temps i rhink you didn't do rsx the right way,or you were impatient.you really need to clean the chips,take your time.

With what I am supposed to clean them? Alcohol did nothing. If I put force I am afraid I will break something.

use a razor blade and be patient

But would that not scratch the chip after a while?
Is VRAM cleaning a must?

Unless you want to have a Overheating Start-Up Warning, then yes, cleaning the VRAMs it's a must, besides you won't have an overheating warning, but rather a loud fan on the start following with a sudden shutdown.

So i would clean thoes VRAMs if i were you, but if you were me, you've already have them clean [emoji23]

vram chip is not the same as cell and rsx die,it's sealed in material similar to plastic and light surface scratching can't harm it.clean it with a razor or heat it up a little if you want to be gentle as possible.little heat goes a long way when cleaning glue and sticky residues of all sorts.

 

[sandungas]

I guess you are having a problem of heights in the RSX now @NewFile
I mean... the old thermal paste on top of the VRAM is "pushing" the IHS a bit higher and doesnt allows the IHS to touch the DIE at the center of the RSX very well

Lot of time ago a guy named eussNL and me was taking a look at the datasheets of most/all VRAM chips used in PS3 and doesnt generates much heat by themselfs, and resists a lot of heat
We was discussing if is really needed to dissipate the heat of the VRAMs and our conclusion was that is not needed, later sony confirmed it when they removed the RSX IHS on superslims

What i mean with this is... you are not having a problem dissipating the VRAMs heat

And dont worry about scratching the VRAMS on top, it will not be damaged by the scratches because the circuitry inside them is way deeper
Lets say... (as an stupid experiment) if you drill a hole of 0.2 milimeters deepth on top of a VRAM probably is going to continue working normally... like if nothing happened

*This is why sometimes i mention that removing the IHS from RSX with a razor blade is something aceptable... because you are risking to scratch the VRAMs on top but it doesnt have much importance
