MSI Trio 3090 water cooler purchase list

Can I ask if anyone has any advice about radiator placement if its on its side?
I am aware the if I mount a rad vertically then the I/O should be at the bottom of the rad.

Does it matter where the I/O is if on its side? Should I place the in at the top , or the out at the top? Does it matter?

Thanks!
 
Port placement really doesn't matter as long as the pump isn't the hight point of the loop (you don't want air collecting in it). Place it however is easiest to bleed.

The whole rad orientation furor has come about because of AIOs that have the pump in the block. If you're rad is then mounted below this, the air will get stuck in the pump, rather than the rad. I think it's fairly rare that an open loop would have this issue unless you are trying to mount the pump on the top of the case or something...

Brilliant! Thank you!
 
Hello all.

I finally got a setup - a barrow gpu block , cpu block , two black ice nemesis 240 GTX rads , 4 corsair fans , a D5 pump and reservoir. I am using EK Cryofuel acid green. I have my system setup on my bench at the minute. Its purely function over form but I dont think it looks bad for my first go!

 
Just spotted your review of the block. Sounds good. Everything required was included? I.e. you didn't have to buy thermal pads or anything?
 
Oh, also! The memory on the back gets super hot and I've seen reports of throttling due to it. I'm going to be getting some of those copper NVME heatspreaders to stick to the backplate, over the memory. You might want to look at it.

Everything was included that you need. Just put the thermal pads where they are on the heatsink that you remove , not where the rubbish instructions tell you to put them!

I currently have a 120mm fan pointed at the backside of the card reducing the junction temps to 90degC with a overclock of +950 memory.
 
Nice one, thanks.

Unfortunately the airflow through my case isn't great as the two fans I can fit both have 60mm rads behind them. I 'm gonna throw a bunch of heatsinks on there and hope it helps.
 
I installed my block yesterday and there's something I'm not so sure about. There are 2 places where heatsinks are removed and nothing replacing them. The capacitors at the back and the little bracket over the chips at the very front. I take it you had the same thing?

I replaced my case and pump so I could go all hard-line. Currently planning the loop with 15mm scrap from a plumber friend before he helps me bend the 16mm.

I left the capacitors alone - exactly like yours. I put the very thin thermal strips on the front chips. I mirrored everything else that was on the OE heatsink.

Did you have to remove this heatsink? Mine wouldn't fit with it fitted. It leaves the chips without any cooling.

Yep ! They didnt mention the removal of it in the instructions, did they ?

I am not convinced of its merit as a heatsink. I think its just a strengthening piece to make the card more rigid TBH

:)
 
The instructions were probably more hindrance than help. Okay cool, it does have thermal pads on the back of it. Just concerned as we're not only removing that heatsink but reducing the airflow to that area.

As an aside, I've ordered some NVME heatsinks and a 92mm fan. I'm going to fit them over the Memory on the backplate and try fit the fan to the PCI slots. Hopefully that will provide good cooling as the memory gets hot enough to throttle the card.

Edit, fits perfect! I know it's more obstructed than is ideal but it's a lot better than nothing. I have to modifying the rad mount tray in the basement of the case, so may cut out the four PCI brackets in the middle and just leave the stubs there so they will still accept something in that slot.

I went with a great big heat sink and thermal pad from Amazon. Tbh the OE card never got near throttling from the memory, and I am now at 88 degC With the heat sink on
 
Is that you mem t-junction temp? You will need hwinfo64 for that.

I didn't want to buy a 3090 but the GPU situation didn't give me much choice and I refuse to fund scalpers. So I have it mining to try recoup some of the money. It's memory intensive and it was throttling the card with mem temp of 106. Underclocking and undervolting the GPU helped but it was still in the 90's with a fan propped on the card.
 
Yes. It’s my t-junction temps.
GPU-Z now has these temps on it as well.

i am under clocking at -300 core, and over clocking mem at +950 whilst running at 80% power ( all settings in MSI afterburner )

88 deg C solid all day and night.
 
Nice, open bench benefits I guess. Airflow inside my old case was terrible as I couldn't fit the watercooling gear and fans ( or rather, fans that didn't have a radiator behind them.)

Flow in the new case should be a lot better
