Question Corsair 275R Airflow and AIO upgrade fit advice ?

[DREDKNOT_2077]

im looking to upgrade my rear aio from my arctic freezer II 120

to either a

Bykski B-RD120-TK60 radiator copper 120mm (60mm thickness)

or a

Aquacomputer airplex radical 4/120, aluminum fins

would either fit in the rear slot of

my Corsair 275R Airflow ATX Mid Tower Case

currently my arctic is

mounted in the rear in a pull con-fig with a single noctua fan with some after market filter mesh

between the case an aio , both ways of config push or pull have no change in performance the pull is

easier to clean with a shopvac from the outside so thats th reason for pull config

Cleaning should be done every 6 months, like it or not, open the case, blow through all components.
I like to keep my CPU cool so my Liquid Cooling has dual Corsair fans pushing air out. (above CPU, top of case)
I could never compromise for running just 1 radiator piece. Is your case that small ?
I would think the fan pushing a good amount of CFM is a lot more important, if you bank on just 1 tiny radiator.
Given the thickness say 120 CFM ?

thanks for that , case size isn't exactly crammed but the cooling in my home isnt great an after a lot different aio an fan config layout i settled on the freezer II 120mm to replace my Corsair H100x that was front mounted at the top with the last 120mm fan at the bottom as intake an 120mm as rear exhaust an 2 x 140mm as top exhaust all my fans were an are noctua indust 3000rpm

the flow was of but not great especially on a warm day worse on a hot so swapped out to the freezer II 120mm an front mounted at the top fan as a pull config which held temps better then the h100x but my gpu still not as good on warm or hot days (inside temps were an are 74 - 77degs) wither it was horizontal or vertical mounted , what did was this to put the aio in the rear as a pull config

with two 140mm as top exhaust with 3 x 120 intake my cpu an gpu when from an peak load temp of 48c cpu an 62c gpu to 42c cpu an 52c gpu in a 77deg room but my big reason for wanting a better cpu cooler

is while the gpu stays at 52 - 54c after a 6 - 8hr run in a 77deg room the cpu does not not sure way but my current thinking is a thinker rad will take longer to reach a heat plateau but also in-general better cooling to an maybe if i could find a compatible fullcover water block for my gigabyte 1660 super oc tie that in too

im just also considered that i might interfere with the airflow over the vrms heatsinks so wither or not the thicker rad would be an issue

RPM means nothing to cooling, CFM does.
But whatever gets you cooler results is good, I suppose. 77F Deg. is normal for a room, I hardly keep mine at 75F.
At idle my cpu is 30C & gpu is 35C according to Speccy. Might be a +5C discrepancy to Bios but still cool.
I pull air from the front with 2x 120mm, I have a crazy pull on the rear though, jet engine, capable of 15K RPM.
I think it's time you reconfigure your cooling to allow for the 2-3 size radiator, if you want to go cooler.
