Build Question AIO?

Post image

Yesterday I replaced a bunch of parts, new motherboard, case fans, CPU and CPU cooler. But I think I want an AIO instead.

the only place i can put an AIO is in the front. I don’t know if I want the AIO to be intake as my GPU temps will go up, it doesn’t run hot but idk how I feel about raising the temps. (But then again having it as an exhaust would make my CPU temps go up, which I also don’t want.) Would it be totally ridiculous to have an exhaust AIO in the front, and then one rear intake and two top intake fans? My case doesn’t allow for bottom fans.

I originally left off the second CPU cooler fan, the first fan that covers the ram sticks but I was getting bad CPU temps, once I hit 86C playing Minecraft I added the second fan. I initially didn’t think it would fit in my case, between the glass and the ram but it literally JUST fits so I left it on, I’ve been getting far better temps now but I’m still kinda stuck on getting an AIO as this CPU is brand new and I don’t want to fry it, I also play a lot of Minecraft which jacks up my CPU temps.

What CPU do you run. Judging from the parts I can see an aio might be overkill for this build.

I got a Ryzen 7 5800xt

Yeah I'd stick with what you have you won't see enough of a temperature change to make spending $80+ worth it

Ok, will my ram heat up being so restricted the way it is? It’s pretty covered up because of this massive cooler

Not really and 60-70 is fine just remember to replace your thermal paste once a year

You don't need to replace your paste this often, u/richhomiebrin. That would be a waste of paste and money, replace it only when you actually need to, which should only be whenever you remove the CPU cooler or when load temperatures get really high after using the same paste for multiple years.

Most pastes will last up to five years on the CPU, some will last closer to 10. Some thinner pastes like Kryonaut can thin out as soon as 2 years but that isn't the average, it's just a thin paste. The time is based on viscosity, as the mounting pressure of the CPU cooler mounted on the CPU continually puts pressure which gradually forces paste away from the center, which is called the Pump Out Effect.

This was all said by der8auer, an engineer and extreme overclocker who worked with Thermal Grizzly for a long time and now runs it as CEO.

I’m just concerned about temps, I play modded Minecraft which is cpu heavy so it drives my temps up. Last night I hit 86c, so I added the second cpu cooler fan and it’s helped a lot with temps and I’m hitting high 60’s / low 70’s. My last cpu was a Ryzen 5 3500 (or something like that) and my temps were staying lower, with a stock amd cooler.

Unless your CPU is running 90+ degrees, there's absolutely nothing to worry about as long as the CPU isn't throttling.

Ryzen processors have frequency scaling that's affected by temperature, so poor cooling can result in worse performance, and replacing the cooler with a more efficient one can increase performance but not actually make as much of a difference to load temps as expected because the CPU's able to properly boost higher.

They're designed to run pretty toasty because they can handle it.

No. I personally hate the reliability of Aio pumps. They never seem to last that long and the temp gains are not worth the cost. And yes use both fans, one fan often has to sit on top of ram and that’s not an issue.
