AIO Cooling VRM Temps

[itsRyansKi]

Hey,

 

I'm just looking for some advice on how to approach it as I'm new to AIO cooling, I've only used air cooling for the longest time.

 

So I bought a 240m Deepcool AIO a few days ago, I've installed it. Overclocked, ran stress tests to test for stability. All absolutely fine.

 

Now when the heatwave came a couple of days ago, the CPU temperature was fine. Sitting around 40 -  45c though the VRM temps were around 50, I also had a random crash on this day and everytime I would start a stress test it would basically crash(CPU at 40 VRM 48 at start). It's now a few days after and the weather is a lot cooler and completing the stress tests are absolutely fine with my CPU only going up to 75c again. The VRM is hitting around 48-53c, I believe that the VRM temp is what made it crash the other day.

 

Is there anyway I can test if it is the VRM? Also what is the best setup for an AIO cooler?

 

My current setup is 3x 120mm fan on the front all blowing in air. Dual rad on top with 2x 120mm then a single 120mm at the back pulling air out.

 

Would I be better to mount the rad to the front and just leave fans on top?

 

Any tips or ideas would be much apprecitated, thank you.

VRM’s are not even a concern until 80c+.

 

How did you validate the CPU OC? 8 hours of asus real bench? If not, validate with that...

I was running it with Cinebench R15 on loop for 2 hours. I will try this over night and see what the result is.

 

Also random question, can mounting the AIO straight to the case cause any problems or? As I know some people mount the fans to the case and I don't know what is best practice.

I would wager the crash is totally unrelated to any cooling you've described in this post. Temps are well under thermal limits and absolutely fine.

 

Mounting an AIO directly to the case shouldn't cause any issues. It's how most are mounted. It's how mine is, for instance.

Yea,  I would use asus real bench to test, 8 hours stress test is the longest option it has. If you have 16 GB of RAM, select 8, if you have 32, select 16 (it can bug out if you choose the amount you actually physically have). Link here: https://rog.asus.com/rog-pro/realbench-v2-leaderboard/

 

As far as where to mount it, it really doesn't matter at all. I typically mount my fans in a pull configuration if I can as that allows for easier cleaning of dust. The rad is where all the dust will collect, so if you put the fans in pull, you have easy access to the radiator face to clean it. Either way though, it makes no difference.
