Or just read the max gpu size on case websiteAmazes me that people will spend around £2k on a GPU without doing a simple measurement first, only takes a few seconds.

Thats not very true.That's the stuff here :-
Honeywell PTM7950 SP Super Highly Thermally Conductive PCM Pad
Buy Honeywell PTM7950 SP Super Highly Thermally Conductive PCM Pad for £4.85 with Free Shipping Worldwide (In Stock)www.moddiy.com
See problem now for people that want to water cool their 4090FE/AIBs (guessing AIBs are using PCM TIM too) is they will need to get PTM7950 pads/paste or use liquid metal, reason is this pad/paste is only second best to liquid metal and normal thermal paste can't match it. So heads up to people taking them apart for thermal paste changes as this is not normal thermal paste but a phase change pad/paste. Used a lot in laptops and sensitive equipment that needs heat removing quickly.
Lenovo laptops uses a custom version pad PTM7950 and called PTM7958, Alienware laptops use Element 31 PCM paste basically a version of this stuff, etc more custom ones too and all highly electrically conductive too, so don't get this on electrical parts like liquid metal. So if you don't know the TIM method used on a device don't just guess it's thermal paste because it's grey and looks like that when removed as that can cause issues later and hot spots. This stuff doesn't weep out (pump out) like thermal paste over time so don't go replacing TIM on a 4090fe/AIBs unless you have new PTM7950 pads/paste version or you want to risk liquid metal.
So you have been warned now and if you replace the paste and wonder why it's running hotter this is why also new cards or PCM TIM change may show higher temps at first few hours until the stuff settles after a few thermal cycles.
This is the paste tube version that can be used too :-

Phase Change Materials
Phase Change Materials (PCM) are often used as matrix materials for thermal interface applications.thermalmanagement.honeywell.com
PCM is used because they know that due to die structure conventional TIM will be pushed out. That's why its also used in laptops. It's not any better than good TIM in thermal conductivity.
Very thick pastes like Thermalright TFX have proven better than PCM in laptop applications so I would be very surprised if it turned out any different in gpu application.
Its not like PCM is a breakthrough material. It existed for years.
You will certainly not need it on properly designed waterblock.

Even the O11D XL struggles with the 4090

I would put that rad in the top of the case, running with tubes up like that is not a good idea, you're pushing air around the loop with it like that.
Edit: or at least in the back of the case where you have room to orientate it tubes down.

Looks like there's room for a triple thick front rad, tons of space
My Zotac fits in the 011D XL pretty nice tbh and that's with a load of watercooling stuff in there as well

Let's hope I can fit 4090/4080 in my 5000d airflow ;D

Love that case, i'm waiting for the opportunity to buy one, at £150 its a bit pricy, normally i would settle for the 4000D but like an idiot i bought a 360mm AIO where what i should have done was buy a 280mm, now i need larger high end cases to fit the rad in the top.
It depends on the version of the PCM TIM used as I said above as an example Element 31 from Alienware is a gallium liquid metal in an encapsulated type TIM.
Alien autopsy: Meet the radical ‘Element 31’ cooling inside Alienware’s new X-series gaming laptops
Here's how Alienware made one of the "most powerful" super thin gaming laptops we've ever seen.

I wouldn't be risking a £2k GPU using the wrong TIM, now I wonder if all the people that had problems with 30 series FE cards was because they used this stuff too and when people changed to normal TIM stated they had worse temperatures after a new application of TIM.
Yes the PCM TIM is really good at not getting pumped out like normal TIM, also Thermalright TFX can't be used on Alienware laptops that use Element 31 and you need to contact Alienware/Dell for a new tube which they supply if you ask them if out of warranty or they will send an engineer out to you to do it under warranty.
There is a reason why I knew when the Nvidia guy said PTM7000 and knew it was a Honeywell PCM TIM as we have had to buy that stuff at work to replace cooling on some of the servers and you can't use normal TIM and the maintenance guide/service manual states to use this stuff only not normal TIM.
That's why I was surprised to hear him state that in the video as this stuff is not easy to get for the general public to replace it.

Yeah it was meant to be £100. Think it covers up to £30,000
Actually the first one (before edit) was right. The £100 minimum for Section 75 protection relates to the full cost of the purchase, not how much you put on the credit card. i.e. as long as the purchase amount is more than £100 (and less than £30k), you can put £1 or even 1p on a credit card and the rest on a debit card and you still get the full protection.
Section 75 refunds
Section 75 protects your purchases over £100 if you use a credit card. This MoneySavingExpert guide tells you how to reclaim if something goes wrong.
www.moneysavingexpert.com
The product or service you're buying must cost over £100 and not more than £30,000 to be covered. Crucially, though, you're still covered even if you only pay a deposit of 1p towards an eligible purchase on credit. You're also covered if you've since closed the credit account you made the purchase with.

Guys I just purchased some PSU - PCIE Cables but they are Corsair ones ( Type 4 ) Will it be ok to use these on my Seasonic PSU ??? I'm hearing mixed opinions online..... Can someone confirm if its ok to use that cable.

I think its to do with like having a panic mode and getting any one that's in stock in the rush. Like every second counts.

I've read that they will most probably have different pinouts and not to risk it.
I personally wouldn't risk it.

No. You will need new cables.

That’s even better then. At least I got the 1 rightActually the first one (before edit) was right.

.So as long as it’s between
£100 and £30,000. I stand corrected. Thank you.
what about EVO

Then why have various YouTube channels been stripping and rebuilding cards and not hitting any issues and not mentioning it at all?
