I'm having issues with my iBUYPOWER AIO cooler for the second time, and I'm considering upgrading. What are some reliable recommendations for a good 360mm AIO cooler? I've heard a lot of praise for the Arctic Liquid Freezer III Pro; is it really as good as people say? Also, what type of coolant should I use for the new pump? On another note, my current AIO has started to randomly slow down my fans, which then speed back up. How critical is this issue, and should I act quickly to fix it? Thanks!

Have you thought about switching to an air cooler? It might be less hassle. If you go that route, you’d replace the AIO unit with an air cooler instead of modifying your current fan setup. Just something to consider!
Honestly, AIOs can be pretty hit or miss. A lot of users run into issues, so if you're not super into the liquid cooling scene, you might want to consider air coolers. They're generally more reliable.
It’s normal for AIO coolers to adjust their speeds based on CPU temperatures. They’re not supposed to run at a constant speed. But if you're noticing drastic drops and spikes like from 2000 RPM to 1200 RPM in a short time, that could be a sign of a problem with the pump or fan, not just regular temperature adjustments.
The Arctic Liquid Freezer III Pro is a solid choice that a lot of folks recommend. It’s often praised for great performance. As for coolant, just stick with the manufacturer’s recommendation unless you want to try something aftermarket!

Yeah, my AIO has been making grinding noises and the fans are unpredictable too. That kind of fluctuation isn’t typical; sounds more like a malfunction.
