the Noctua NHD 14 widely regarded as one of if not the best air cooler on the market this is a six heat pipe duel tower cooler that includes a 140 millimeter fan in the center between the two towers a 120 millimeter fan on the outside of one of the towers and then it should you so desire I believe you can actually install an additional 120 millimeter fan on the other tower so this isn't a push-pull contraption push pull push configuration this one's doing pushing and pulling through radiator or heatsink fins and down here make contact with the CPU somewhere in there you can see that they've cleverly designed the height to be just barely acceptable for high high profile memory modules such as the muskan red lines that I am using here today all right so I have for the longest time wanted to test this CPU heatsink against this CPU liquid cooling unit so this is the Corsair H 70 is a - density high thickness single 120 millimeter radiator liquid cooling system so I can tell you guys right now any thin low profile radiators system such as a Kula dqo or an H 50 is going to get smoked by this bad boy I mean it's fairly simple science at this point more surface area far less surface area for the for the thin profile radiator liquid cooling units so that's that ain't going to happen for them but the h 7e might stand a chance so what I'm going to be doing today is I'm going to take the H well first I'm going to test the NHD 14 on my four point seven gigahertz core i7 2608 this is with fair / fair bit of over voltage so we've got a fair bit of heat to dissipate here I'm going to first test the NHD 14 and its stock configuration then I'm going to take this one 20 mil fan another NFP 12 I believe it is a 1300 or whatever it's called the the one 1300 rpm pressure fans so the one with the blades like that not the other one and I'm going to install two of those on the H 70 and see how it performs compared to the NHD 14 I'm very excited about this because the H 70 is the highest performance single 120 millimeter liquid cooling prefilled unit and the NHD 14 as I mentioned before is one of the highest performing air coolers on the market so let's see which one wins this heavy weight tilt so here I am running eight instances of prime95 on my core i7 2614 purger is 74 degrees in the minimum one is 68 so we're going to call it sort of somewhere in that 68 to 75 now 68 to 75 degree range on the NHD 14 so I just put the H 70 with the two knocked with hands onto the CPU you can see temperatures are a touch higher already and you have to note that unlike an air cooler where the heat pipes basically reach their maximum temperature heat carrying efficiency etc right off the bat a liquid cooling unit actually takes a while to reach equilibrium where the liquid inside has to heat up to the point where it increases the efficiency with which the radiator can exchange the heat between the water and the air and the higher the temperature the liquid inside the more heat is able to be exchanged until it reaches a point where it no longer continues to rise with a constant heat load so I'm going to give it some time to see how high it goes but I think we can already see that the D 14 comes out ahead with the same fans alright well looks like we've settled into a max temperature here 88 degrees on the highest court 81 degrees on the lowest core running prime95 eight instances of small FFT and thank you for checking out my video of the NHD 14 versus the Corsair H 70 don't forget to subscribe to Linus tech tips from our unboxings reviews and other computer videos yeah that's pretty much it don't forget to subscribe
