Customer Questions & Answers
-
Question:
Is the Liquid Freezer II 420 compatible with Intel's Alder Lake processors?
Answer: Yes, it is compatible with Intel's new Alder Lake processors - Socket LGA1700. -
Question:
Does the Liquid Freezer II 420 have integrated cable management?
Answer: Yes, the PWM-cable of the fans are integrated into the sleeved tubing. Thus there is only one short cable visible from the pump to motherboard replacing the usual cable mess. -
Question:
Does the Liquid Freezer II 420 provide additional cooling?
Answer: Yes, an additional 40mm VRM fan (PWM controlled) next to pump can provide extra cooling for the base and voltage transformer. -
Question:
Does this come with a mounting bracket for LGA1700?
Answer: ARCTIC Liquid Freezer II 360 A-RGB Rev2 comes with the bracket, but Rev1 does not. The specific revision received can be hit or miss. -
Question:
Is this the latest revision? Does it come with the AM4 mounting bracket?
Answer: The version received is the second to latest revision, and it includes the AM4 mounting hardware. The purchase is from the Arctic store, which is reliable for providing the correct revision. -
Question:
Can the LEDs be disabled without installing software?
Answer: Yes, there is a separate cable to attach the RGB header. It can be left detached to disable the LEDs. -
Question:
Does it come with thermal paste pre-applied?
Answer: No, it does not have thermal paste pre-applied. However, it includes a small tube of Arctic's own thermal paste for self-application. -
Question:
How do I change the color of the fans?
Answer: Assuming it is plugged into an ARGB header on the motherboard, the color can be changed using the software provided by the motherboard vendor, such as Asus' Armory Crate. -
Question:
Does it come with the new pump gasket and a bracket for the LGA1700 socket?
Answer: It includes the new bracket, but the new pump gasket may not be included. The mounting system and one-time use stick on gaskets for the motherboard may not be preferred by some users. -
Question:
Does it come with thermal paste?
Answer: Yes, it does come with good quality thermal paste. -
Question:
Will this fit on the Asus ROG Maximus Z690 Extreme with Intel Core i9-12900K CPU without any issues?
Answer: Yes, this cooler will fit on the Asus ROG Maximus Z690 Extreme without any modifications. The LGA1700 kit is included, and the VRM fan should be oriented towards the top of the case.
ARCTIC Water Cooling Systems Editorial Review
The Arctic Liquid Freezer II 420mm AIO cooler is a very quiet cooler that can cool high-clocked CPUs with ease. The cooler comes with Arctic fans that work outstandingly at CFM and dB levels. The cold plate is as flat as possible while there is no backplate in the pack but it can be managed with the stock one. The hoses are long enough for most cases but they are too short for larger ones. The installation process wasn't too hard but Arctic doesn't include a manual and the screws and brackets are in a ziplock bag. It cools CPUs efficiently and comes with necessary parts but be careful when mounting it on the CPU. It is a huge cooler, so make sure that your case can fit it.
