Verdict
ARCTIC Liquid Freezer III 420
9 / 10 Expert Rating
One of the best value-per-degree AIOs available at any radiator size, now in its largest non-Pro form.
Jonsbo TW3-240
6.2 / 10 Expert Rating
A basic, inexpensive 240mm AIO that only makes sense for older, legacy-socket systems given its dated official platform support.
