Honestly for that Phoenix heat, skip air. Try the Corsair iCUE H150i ELITE CAPELLIX XT 360mm or maybe the be quiet! Silent Loop 2 360mm AIO. Super reliable and cooling is solid.

Late to the party, but dealing with that Phoenix heat is brutal. Are you using a mesh front case with enough clearance for a 360mm radiator? If your case supports it, the Lian Li Galahad II Performance 360mm AIO is top tier for thermal transfer. Also the EKWB EK-Nucleus AIO CR360 Lux 360mm keeps things steady under heavy load. What case are you currently using for this build?

Building on the earlier suggestion, sticking to an AIO is definitely the safer play given those ambient temperatures. You've already got some solid recommendations like the Arctic or Lian Li models, which are reliable, but honestly, even the best cooler can only do so much if your airflow isn't sorted.

• Ensure your rad fans are set to exhaust if you have a cramped case
• Check your pump curves to keep them running consistently
• Dont ignore the motherboard VRM temps since they bake in that heat It reminds me of this one summer back in the day when I lived in a top-floor apartment. My AC unit completely died in July and I had to rig up this DIY evaporative cooler using a bucket of ice and a desk fan just to keep my server from throttling. I spent three days straight checking the ice levels every hour like a frantic lab tech. It was honestly a disaster and I think I aged five years that week trying to keep my hardware alive. Anyway lol, sorry kinda went off topic there. Just prioritize that pump reliability above all else.

Phoenix heat is no joke man! Honestly if you are pushing an i9 in that climate, air just wont cut it anymore. You gotta grab an AIO to move that heat away from the chip immediately.

• Arctic Liquid Freezer III 420mm AIO
• DeepCool LS720 360mm AIO These coolers are absolute beasts. The radiator size makes a massive difference, especially with ambient temps being so high. You'll love the performance jump!
