    XFX 7900XT merc 310 high junction temperature

    Hello, Sad to hear, please make sure that the 3mm thermal pads are correctly placed on the backside (M & N) (Not on the caps! but next to them, See page 10 in this thread)

    XFX 7900XT merc 310 high junction temperature

    Will be interesting to see how it ages for you because my temperatures have been increasing quite a lot in just one year (around 15-20c increase on hotspot now). Using the provided AlphaCool paste, noctua wouldn't work at all for me (probably used to little) ;) Will move over to KryoSheet when...

    XFX 7900XT merc 310 high junction temperature

    Yeah, it's really annoying to take the loop apart to change/adjust these things, it's definitely inconsistent result each time even tough it feels like I do exactly the same every time. Looking at the temps it is time for me to replace the thermal paste, not even 1 year old paste that has...

    Your thermal pads are NOT in the right location. The thermal pads on the back should not sit on the caps(!), they should be next to them. Above setup will bend the PCB in that way that the big frame-like thermal pad behind the GPU-chipset won't create the needed pressure towards the waterblock...

    Just out of curiosity, is the graphics card installed in a horizontal or vertical orientation? If horizontal, do you have any sort of sag support installed ?

    Alphacool Waterblock/AIO for 7900XT/XTX planned ?

    I noticed the same thing, if placed according to reference/stock heatsink you will get gpu hotspot issues since the pads on back of the gpu core wont have sufficient contact due to these pads are to thick to rest on these thick capacitors. These capacitors should not be needing cooling in that...

    Rust red radiator out of the box?

    I could see this on my EK radiators at some angles as well, especially on the thicker one (45mm). If I would guess the reason behind it's probably connected to the efficiency of the radiator, more paint = less effective. But at the same time, hard to tell exactly how bad it is just looking at...

    Alphacool Waterblock/AIO for 7900XT/XTX planned ?

    Some quick results, lowered temps by 15-20c core. About 12-13c hot spot compared to air cooler with 60% fanspeed (noisy). My computer is now silent even longer high load situations, all fans at 700rpm :) ##Updated values for Benchmark stressing: Stock OC-mode# Core: 40-42c Hot Spot: 64-67c...

    Alphacool Waterblock/AIO for 7900XT/XTX planned ?

    I will share data and pictures. Main focus with my custom loop is to make the computer quiet even in high load situations, meaning that I will keep my fans at relative low speed (140mm, max 900rpm) in all situations (which is not possible with Merc310 air cooler with 400-450w powerdraw during...

    Alphacool Waterblock/AIO for 7900XT/XTX planned ?

    I have now received the Merc 310 waterblock, just had a quick go-through and everything seems to be included. Will mount it as soon as my ordered 7800X3D have arrived, I just want to split and redo the water loop once if possible :)

    First GPU block install, advice

    Maybe this is on purpose by you, but I think your pump is connected to the GPU block outlet port. It will affect the performance since it's not connected as designed.

    That wont help me though since I didn't order this directly from Alphacool-site. #Update, according to my supplier the package have been sent now.

    Alphacool Waterblock/AIO for 7900XT/XTX planned ?

    It seems like the delivery date once again have been moved forward to "June 2023" for Merc 310 block, but will probably be moved to 2024 at this rate. Seems like the only viable option for me will be to buy a 7900XTX reference design block from EK and modify it. I think it's a bit sad because...

    Alphacool Waterblock/AIO for 7900XT/XTX planned ?

    Okey, thanks for answering Eddy :) . A bit odd that they are not provided pads since all the 7900XTX third party air coolers that I have looked at have pads for the coils as well, also EK's 7900XTX blocks have them.. Not an expert at all but It did lower coil buzz on my prior 3080 card though...

    Alphacool Waterblock/AIO for 7900XT/XTX planned ?

    Now you are being bombarded with questions, I have an additional one;) Since your Merc310 WB kit does not come with thermal pads for the coils (according to the manual), what thickness on thermal pads do I need in order to solve that? Why I am asking is because it will somewhat lower the coil...
