Cool GTX
Good to see you,
 
For layout - I'd search for a tear down review with good photos
 
maybe this will help EVGA GeForce RTX 3090 Ti FTW3 Ultra Review - TechPowerUp
 
FAQ # 59822  What are the thermal pad sizes for my 20 or 30 series graphics card?
 
(excerpt)
 
FTW:

3090/3090Ti – Cooler:
Width: 6.5mm Length: 7.7mm Thickness: 2.75mm QTY: 1
Width: 14mm Length: 53mm Thickness: 2.25mm QTY: 2
Width: 14mm Length: 37.5mm Thickness: 2.25mm QTY: 1
Width: 12mm Length: 15mm Thickness: 2.25mm QTY: 1
Width: 5mm Length: 110mm Thickness: 2.5mm QTY: 1
Backplate:
Width: 14mm Length: 10mm Thickness: 2mm QTY: 2
Width: 51mm Length: 12mm Thickness: 2mm QTY: 1
Width: 38mm Length: 12mm Thickness: 2mm QTY: 1
 
I do have some Gelid Extreme 2.0 and 2.5 on hand would need to order some 3.0, think that would be okay? I see lots of 3090 pcb layouts that say what those pads are and where they go but 3090 Ti not so much.
 
 
Good to see you as well

Dear repo1979,
 
If it is a model 24G-P5-4981-KR then the thermal pad sizes are included below in mm.
 
Location - (Quantity x) Length x Width x Height (mm)

I'm looking to see if anyone has or knows where to find the layout of the pads and sizes so I can put the air cooler back on my card. I did send in a support ticket to Evga as well but hoping someone here has info on hand.
 
Been awhile since I have posted here but hope everyone is doing well.

Do you have a diagram to show, wanna make sure I get the right pads ordered the first time. The Pads you listed dont match what the link shows so wanna make sure, that is my card model number as well. And Gelid has 2.0 2.5 and 3.0 pads are those okay? Your sizes you listed dont math what CoolGtx posted

Dear repo1979,
 
The post above has the correct sizes for thermal pads for the model 4981 card.
 
I do apologize as I do not have a diagram to show you.
 

repo1979
Is there a diagram that shows where to place the pads and I see your sizes are different that whats in that link that was posted

Dear repo1979,
 
I do apologize as we do not currently offer thermal pads, but you are welcome to use whichever thermal pads you do prefer. 
 
Please do keep in mind that there will also be the need for Thermal Putty and Thermal Paste.
 
 
 And where does the Thermal Putty need to be applied? I dont recall seeing putty on there when I put the waterblock on the card, yes Thermal paste on the die for sure

UPDATE: If you are using GELID EXTREME PADS see below
 
Pads need to be 2mm on the die side for the Evga 3090Ti cards and 3mm on the backplate are perfect, it would of been nice if Evga still sold the stock pads but the GELID EXTREME pads in 2mm and 3mm are all you need. Hope this helps someone else looking to repad their card.
