Ray,
Make sure that that the PCIE slot looks okay, ie. not loose, no hairline cracks in the motherboard. These enormous cards place a lot of strain on the slots, all depending how they are secured. Can’t remember which case you got, but is there any type of support for the end of the card that is closest to the front of the case?

Very difficult to examine the slot or mobo. I was expecting there to be some support at the opposite end to where it’s attached to the case. It uses 3 slots and screws such is the size of it. If there was a crack you’d imagine that would have happened in transit but it was fine for Thursday afternoon and all Friday. They had put lots of protection inside the case which I removed very carefully.

The replacement needs ordering and should be with Chillblast tomorrow and me either Wednesday or Thursday.

The case is a Fractal Design Meshify 2 Compact. Apparently the MSI is the only make that will fit.

Is your graphics card virtically mounted or direct to the mobo?  Mine is direct to the mobo and ASUS sent along a support for the rear end of the card to take stress off the pcie slot..  with these big 4090's its almost a requirement if you are not vertically mounting the card.

Direct to the mobo. You would imagine if the card required support at the other end MSI would supply the part and Chillblast would fit it. I’ll ask Chillblast if it needs that support. But they build PC’s professionally so you’d imagine they would know if it was required.

Even if it is not the problem, a support is a good idea.
I use one of these.
It is both cheap and effective.

Here’s a comparison of the Ventus (faulty) and the replacement (Trio) which I’ll have in a couple of days.

The Trio ships with a support bracket whereas the lighter Ventus doesn’t appear to need one.

The maximum size of card my case can support is 341mm or 360mm depending on the slot used. The Trio is 337mm long. Snug fit!

@Reader, just read your post. See mine. It ships with one.

Did the PC arrive with the graphics card installed, or with it and boxed, as is apparently best practice?

Already installed but with lots of packing around it.

It must be a tricky decision for the vendor, do you risk damage in transit, or do you risk damage
by the unknown abilities of the customer to install the card themselves.
Then they send out a replacement but no suggestion of sending someone to fit it for you.
My friend's was also shipped with the card installed, but it might only be a coincidence.
I build my own, so it fortunately is not a decision that I have to make.
As Jason points out, graphics cards are now big and heavy things.
My own PC almost needs a crane to lift it.    

@Reader, if you’d seen the amount of packaging around the installed 4090 you would probably agree that it was more than sufficient. I used to build my own until 2018 when I felt systems were becoming too complex and I wasn’t getting any younger. I know you pay a premium for a warranty but after this situation I’m glad I went down that route.

I’m hoping there won’t be any issues fitting the new card with just 3mm spare. There is another slot that has more latitude but the slot next to it needs to hold the bracket and that is currently occupied by a USB2 bracket connected to USB2 headers on the mobo. I’m not sure if the wires will be long enough to read the other spare slot.

Do you have a full size case?

This is the case: https://www.amazon.co.uk/gp/product/B07S8Z5C82/ref=ppx_yo_dt_b_asin_title_o00_s01?ie=UTF8&th=1

It was on offer at the ridiculous price of £66.07, so I grabbed it before they changed their mind.
Today's price is equally ridiculous, in the other direction.
The graphics card is a 3080ti, 320 mm long and there is another 80mm before it reaches the front fans,
so if there was such a thing, it would fit a card up to 400mm long.
It's in a corner and hard to photograph, but here is my best shot:

I notice that I still haven't taken the protective plastic off the glass.

I am not constrained by space, so I went for a fairly big case when I built this close to a year ago. Despite being an old f@rt at 71, I went all-in on colours 😂, including on the support for the 4090.

I use a box of playing cards:
Works very well and was just the right size.
For transportation this won't work obviously, but it is good practice to remove heavy GPU's and CPU coolers before you do so.

Does anyone have an opinion on the cause of this frustrating problem? Signal to monitor lost and case fans running to maximum even when the system is not under stress. Not just once but multiple times in an hour or so.

For me it points to a faulty GPU. Chillblast support agreed. Any other possibilities?

Double check that the GPU is seated correctly and also double check its power supply cables. Its a big heavy card and may have become unseated during shipping.

But it worked fine from Thursday afternoon to Friday afternoon. With nothing having changed overnight the problem started Saturday morning. Another heavier card now enroute with a holding bracket which the problem one didn’t have.

Chillblast have just replied and suggested this which I’ll try should the supplied bracket prove tricky to install.
