Hi everyone
I just got an custom aio cooled rtx 2080ti (originally MSI RTX 2080 Ti gaming trio). Im planning to flash galax bios on it which should allow the board power limit to go from 330 watts to 400 watts.
Im wondering if these vrms (red circle on image) and other components here need more cooling? The vrms on the other side have a fan pointed at them. If not would it then be fine at 330 watts?

Also this is my first post on any kind of forum thread ever so sorry if my post is little strange.

I would definitely cool that row of power stages. Even the ones under the fan would benefit from a heatsink, especially if the back of the PCB isn't thermally coupled to a metal backplate.

As far as i can rember the rule of thumb for those cards was to touch the hdmi port after a gaming session.
If you actively have to cool your finger afterwards it is time to upgrade.

ps my record was 72 C / 161 F measured on the hdmi port itself

Does the backplate actually cool the VRM area of the card? Most are cosmetic/structural...there needs to be some kind of thermal interface material connecting the VRM area to the backplate for the backplate to help cool it to any meaningful degree.

Yeah you definitely want actual cooling for your VRMs for a daily card. I honestly think it's kind of negligent that NZXT (and Corsair with their XG3) don't provide an actual VRM heatsink solution for their GPU kits, just a fan and a prayer.

Something like These (Amazon link) would be ok and they come with thermal tape pre-applied.

If you're going to be really pushing the card, you may want to look into a DIY solution... Some examples of my VRM cooling for hybrid cards (water blocked, but same principle as AIO hybrid):

Hi, i checked and there is thermal padding for the core and memory but none for the vrm. However I ordered a pack of raspberry pi cooling heatsinks. Ill be installing them on the critical components https://www.amazon.de/-/en/dp/B0C2HW56YJ?ref=ppx_yo2ov_dt_b_product_details&th=1

Hi, thanks for your reply! In fact the GPU came with an RTX2080ti block. However I don't have the other parts for an custom loop. Those parts are expensive! I could just order an better GPU instead.

What parts you dont have? By looking at pics, you already have costume loop

Hi again everyone!

I have my heat sinks now and fan. There are 40 small heatsinks with 4 different sizes. I'm wondering what are the critical components on the PCB which would benefit from them. Im thinking the memory around the core but what else? What parts of the VRM and power stages tend to get hot? I tired to look into heat-maps or heat pictures but I havent found any.
