Installed XG7 GPU block, backplate hot

Hi everyone,

 

I transformed my PC into my 1st watercooled PC today :-). Installed the Corsair XG7 Water Block on my MSI RTX3090 Ventus 3x OC and all is working well it look like.

 

Under heavy load (MSFS on Ultra) CPU is stable at 63C and the GPU at 63C as well (full throttle). Running for an hour now and temps are stable, all good I think.

 

The one thing I notice however is that the backplate of the XG7 gets very hot, too hot to touch. I'm guessing between 80-100C.

 

Question: Is this normal? GPU temp in MSI Afterburner says 63C but the backplate is much hotter I think.

 

Many thanks for any advice you can give.

 

Johan

How much radiator real estate do you have? Assume you have checked all of the air is out of system?

 

I have a Corsair 3090FE Waterblock on order. It's presently running outside of the case via a riser cable, and like you, its very hot to touch the backplate!

 

So expecting a similar experience when the block is on, but not so high temps. So I have decided to add a backplate water cooler from mp5works.com which hopefully will help.

 

There are a few YouTube video reviews, and other reddit forum posts etc about it.

 

Might be worth a try, if you can fit one in.

 

I'll post my mp5works backplate temps soon (my main Corsair block has just shipped but status says its still in Taiwan).

HI, I have 2 240 radiators and besides the GPU am cooling the CPU (AMD 5900x). I have ordered the Corsair commander so I can monitor the water temp, but given the GPU & CPU temps I think I'm doing ok in that area.

 

I read in some other forums that 'hot to the touch' doesn't really tell you that much so with the Commander I can attach a thermometer and know temps more accurate, until that time I'll make sure the memory is not overclocked.

 

I'm intrigued by the backplate cooler solution but it's not clear to me how you integrate that into an existing loop, I have flexible 1/2-3/4" tubing but for the BPC the tubing is a lot thinner. Any idea (or links) on how that works?

if you have a corsair pump/res with the thermistor installed, you most likeky have a thermal sensor input on your motherboard, a 2 pin heade somewhere.

Look up your manual, and you may already be able to monitor the temperature of your coolant ;)

 

Hi LeDoyen, had the same thought yesterday and checked my MB manual (ASRock X570 Steel Legend) twice but no such header that I can find.:bigeyes:

The MP5Works backplate block comes with G1/4" fittings that the thin tubes fit into. So I think there are a couple of options to then fit to your loop, either plug the MP5Works fitting into a standard Corsair Y splitter, or into the other side of the GPU block being careful to keep the flow input / ouput consistent. The instructions are pretty clear on this. The chap from frame chasers says in his youtube video review to check the connection to the backplate is definitely good, so I will use a temp probe linked into the Commander Pro, and might consider using some type of heat resistant glue to ensure a firm fit, especially as I'm vertical mounting the GPU.
