Modern processorskeep scram raging , and it seems likeCPU coolersjust keep getting bigger to accommodate them . There are some rightfully grotesque modernistic central processor ice chest — specially passive models designed to operate without any fan at all . It makes you marvel what is the biggest CPU cooler ever made ? Is it one of these previous modern lusus naturae ? Or has a cooler from the past beat them to the punch ?

I did a little deep dive into CPU tank account to obtain some unfeignedly massive coolers — and one that reigns supreme to this Clarence Day .

SilentMaxx Titan

The largest CPU cooler ever: 9.6 x 6.7 x 5.1-inches

In full term of filmy size and weight , the SilentMaxx Titan holds a definitive lead . It is an absolute mammoth of a cooler . Measuring almost 10 column inch along , and close to7 inches wide , there ’s no other cooler out there with the sheer volume of this affair . It weighs an unprecedented 2 kilograms , which is just under 4.5 Ezra Loomis Pound .

It ’s designed to operate as a passive cooler , with the power to handle up to 145 watts . Strap on a couple of gamey - performance fans , though , and it ’ll cool just about anything and do so quietly , too .

Unfortunately , you ca n’t buy this ice chest by itself , but it is available as part ofSilentMaxx ’s custom - built quiet PCs .

ProlimaTech Genesis

The broadest CPU cooler: 5.7 x 8.5 x 6.3-inches

Only falling dead of the very top spot by an column inch or two , the ProlimaTech Genesis ’ dimensions are some of largest among its gigantic air cooler companions . If you dice it ’s volume , it ’s simply vast . It takes up   an enormous amount of intimate space in a PC case , giving it the silver-tongued decoration on our coveted leaning of the with child of processor coolers .

Released in 2011 with musical accompaniment for the then - recent AMD and Intel processors on Socket 2011 / FM2 , as well as many generations of aged processors , the ProlimaTech Genesis is a immense cooler with a unique excogitation . It ’s like a dual tower cooler , but with one of the heat sink oriented horizontally . This allow purchaser to utilize a sports fan to blow down onto their RAM and other components for summate system cool , while a second heat sink on the rear could be configure with up to two rooter in a push - clout configuration . Due to their placement , the idea was to wash up that air directly out the back of the casing .

Unfortunately , its sizing could n’t quite go up to the hype . AsBit - Tech reported at the fourth dimension , while it was reasonably in effect , the downsides to the distinct configuration did n’t outweigh the positive .

NoFan CR-95C

Another unique design: 7 x 7 x 5.8-inches

Another classic from the archive of CPU cooling history , the NoFan CR-95C is a cylindric passive cop cooler that was released in 2011 and reviewed rather well at the time . Hexus give ita solid thumbs - up for its telling cooling performance and whole silent surgical procedure , while review its jumbo size and — for the time — high price tatter . At a heel price of $ 110 , it would be around $ 150 today when adjusted for inflation .

With a thermic design king ( TDP ) of 95W , its ability to work with the very top chips is modified , but to give credit where it ’s due , the NoFan CR-95C was still being used in some builds byFully Silent PCsas of 2021 .

It certainly hosts a unique look , as well as offer believable passive cooling execution . One of these would in all likelihood perform fantastically if it was saton top of a 7800X3D — take over you could make its mounting square bracket convulsion .

Ice Giant ProSiphon Elite

A modern marvel: 6.5 x 10.1 x 4-inches

come by many tech influencers as the all - in - one watercooling slayer , the Ice Giant ProSiphon Elite launched in 2021 to vast fanfare . alas , it did n’t quite live up to those expectations , and sees steady competition from smaller cooler like the iconic Noctua NH - D15 . It use gravity - driven high temperature pipes , so it only works in one of a few configurations , make water mounting a little spot more tricky . Its sheer size does n’t facilitate there either , although in fanless musical mode , it is impressively thin , at just 2 inches .

Still , when one of your other dimensions is the enceinte among any CPU cooler , being a piece passementerie in another does n’t do much to make your visibility more silklike .

TheIce Giant ProSiphon is still readily available , though at $ 170 , it is very expensive .

Noctua NH-P1

The best modern passive cooler you can buy: 6.2 x 6.1 x 6-inches

When the Noctua NH - P1 is the smallest cooler on a listing , you know you ’re walking among behemoth . Despite not quite taking up as much space as the other unveiling on this list , the Noctua NH - P1 is still an absolutely monolithic cooler . design for passive military operation on the in style generations of AMD AM4 and AM5 processor , as well as Intel ’s LGA 1700 chip ( and a number of honest-to-god generations ) , the Noctua NH - P1 is arguably the best passive CPU cooler available today .

Designed to treat mainframe up to 100W all passively , or even more with a still rooter attach , the Noctua NH - P1 is a powerful CPU cooler and is arguably the one to commend on this list if you need a plainly enormous ice chest . It ’s not much to look at , but then , are any of Noctua ’s designs ? I do n’t mind the brown myself , but it ’s not a gang - pleaser .

you could purchase this cooler from a mountain range of retail merchant , for around $ 110 .
