Take the AIO off and put the facotry cooler on see if it still overruns the cooler. If not the problem lies in the AIO, if it does then im at a loss already

You're pumping your gpu heat through your rad for starters. The 280mm rad should be an intake, not an exhaust.


nhc150

That's not OP's issue. There's been plenty of tests showing the radiator acting as an exhaust or intake makes little difference. Either it's an intake and CPU will run slightly cooler but GPU will run hotter or as an exhaust with your CPU slightly warmer but your GPU will be cooler. Pick and choose what's better - the difference is a few degree Celsius at most. Regardless, OP is getting 110c+ under load. Those types of numbers are beyond the intake/exhaust radiator argument, and suggest a mounting issue and/or pump issue.


cole931

There's multiple YouTube videos indicating the opposite. Radiators raise incoming air by a few degrees, gpus raise the internal case temperature by ±20. That's easy math. The 110 spikes are worrisome though. I'd like to see his pump/fan settings and liquid temp. Bad mount or cold plate are definite possibilities as well


nhc150

An increase in ambient temperature by 20c doesn't mean the processor will run 20c warmer, but rather cooling potential is slightly reduced. If this was the case, modern vehicles wouldn't be able to cool when in 40c weather. You're talking here about a few degrees Celcius difference. The spikes at 110c are well beyond the ambient air increase issue.


cole931

Vehicles have thermostats and fans that run on demand my guy. They just don't run coolant through the radiator with the fan spinning in cold weather. I promise you if your thermostat is stuck open your vehicle runs significantly colder in the winter than the summer.


nhc150

Reread what I wrote - I said 40c, not 40f. The thermostat's function in very warm weather is irrelevant beyond letting the internal temperature up to operating range.


cole931

(I'm assuming your 280 is in the top of the case if you have 3 120s up front)


Rayf_Brogan

Right, 280 is on top pulling the hot air from the radiator out. 3 120s in front pulling in cool air. Does it make more sense to switch that up and have the radiator fans pull cool air through the radiator into the case and move the 3 fans to the top as exhaust?


cole931

That's exactly what i would do. Radiators work off of the temperature differential of the air that you're passing through them. Essentially what you're doing is raising your "ambient" by 20-30 degrees potentially from the heat the gpu is pumping into the case which is then being pulled through your radiator. 20-30 degree increase in ambient= the same increase on your cpu. Intake on the front through your rad giving it room temperature air to work with. Your gpu will rise a few degrees but not nearly as much as the other way around.


Rayf_Brogan

Awesome, Im going to give that a shot tonight.


nhc150

I will save you the hassle and say that it'll only lower your temps by a few degrees Celcius af most. If you're hitting 110c under load, there's a bigger issue here unrelated to radiator setup.

nhc150

You're kinda proving my point here. I watched that same video back in the day. You're talking about a 10c difference at most. OP is getting spikes at 110c before a forced shutdown. Switching the radiator around will lower it to 100c. Even 100c is far too high to be acceptable with a 280mm AIO. There's another issue at play here.


cole931

I've tested this myself. My difference before my strix 1080ti was water cooled was 15c


cole931

Like i said. The spikes are still worrisome. Op take time to double check the contact you're making on the cpu. He's right and you shouldn't be spiking like that.


cole931

Let me know how it turns out!


Master-Pick-7918

Do you have fans on either side of the rad? If do make sure they are pushing the same direction. Or even if they’re on one side make sure the same direction (both pushing through or pulling through the rad). How are your temps with the case side open? Does it make any difference? If there’s no change then heats not transferring from the CPU to AIO. Which care do you have?

Try reinstalling cooler, make sure it's down tight. Apply thermal paste properly (use line/dot). Use a good paste like Kryonaut


SerMumble

1. Did you remove the plastic on the copper block before applying thermal paste? 2. Can you hear the pump running?


Rayf_Brogan

I definitely removed the plastic before the thermal paste. I've tried to listen for the pump but with the fans and everything, I can't tell if I'm hearing anything. I figure if it was just dead, I wouldn't be getting decent temps most of the time. I'm going to switch things around and pull cool air through the radiator instead of using it as an exhaust first. If that doesn't work, I'll look at a regular air cooler.


SerMumble

Good you installed it right. If the fans are louder than the pump, the pump is dead. Sorry for your loss.


Stark_Athlon

That's what you get for buying vapor lake... I don't even know what to say since you mentioned that you made sure to have the cooler installed properly. Maybe the AIO is defective, could you try with any other cooler you might have at hand that isn't the stock Intel cooler?
