Melodist Hello there, Is it worth replacing my NH-D15s for a 360mm AIO? What temperature improvement would I gain compared to the Noctua? Reviews are so inconsistent and never tested with a hot CPU such as the 9900k which really annoys me. Proper outlets are even worse with their CPU tests from 4 years ago so they don't have to refresh their current Cooler values for future reviews which tell nothing about the actual performance. I've actually found this chart but there isn't the D15s listed... #1 · Sep 10, 2019 Hello there, Is it worth replacing my NH-D15s for a 360mm AIO?

Much better at cooling my Skylake-X CPUs than my D15s. #4 · Sep 10, 2019 And what the heck is that: I currently own the NH-U12A which makes me wonder if it is even worth upgrading to the 15s https://www.overclock.net/forum/attachment.php?attachmentid=294602&thumb=1

#5 · Sep 10, 2019 (Edited) I would say keep your NH-D15s running with dual fan setup? Here is a link for the s version vs AIO's srry no 9900k it just gives you an idea. https://www.guru3d.com/articles_pages/noctua_nh_d15s_cpu_cooler_review,7.html This link is with the non S version of the NH-D15 vs AIO's this time WITH the 9900k https://www.techspot.com/review/1730-intel-core-i9-9900k-core-i7-9700k/page3.html Your talking about 4 to 5c difference at FULL load compared with AIO (first link) and we both know you never run your system at 100% load 24/7. And coming from some one who uses custom water cooling. If your really want lower temps then go with a simple cpu only custom wc set. Which nets you around 320 - 350 bucks, better use a good cpu block. #6 · Sep 10, 2019 I went from a Noctua NH-D15 to an NZXT Kraken X72 and saw a very small gain of 3-5C on my 9900k @ 5GHz. This post has been deleted Show more replies 0 Reply #7 · Sep 10, 2019 (Edited) My nephew had NH-D15S cooling his 5960X at mild OC and sold it on kijiji to replace it with x72 and apparently Kraken is very good cooler, now he regrets it, the temperature at MAX is 2-3C better just as the person above stated, but the noise level its significant, last I spoke with him, hes going back to NHD15S. I have system with custom loop and 6950X and another system with NHD15 cooling another 6950X and tbh. If it wasn't for my 3 gpu's I wouldn't bother with water, unless your case is really cramped and you have very poor airflow, NH-D15S handles any CPU perfectly fine I would stay with Noctua #8 · Sep 28, 2019 (Edited) This might interest you: https://forums.overclockers.co.uk/threads/air-vs-aio-18c-drop-in-temps.18865693/ A 9900k working hard will put about about 230w and 150amps. Those are the figure you want to focus on. #9 · Sep 28, 2019 There is a thing with 360mm AIO's, most of them are noise optimized meaning they have pretty low RPM fans, which isn't ideal for heavy OC and prolonged stress testing. H150i really starts to shine with the fans swapped to Noctua, insteaed of the stock ones. I've had H150i, ML360R RGB and now the X72 and have to say H150i is by far the best. CM had a gurgling pump, Kraken has the typical Gen5 crackling/rumbling. #12 · Sep 28, 2019 The fans on newer Corsair units are very decent ML-series but in OEM version, sans RGB. The biggest culprit is their low max RPM. #17 · Sep 29, 2019 Do you really need to replace them to cool high TDP CPUs though? 0 Reply #13 · Sep 28, 2019 The Corsair H150i has fans with 1.78 mm-H2O static pressure, which is bad. They might be silent, but just horrible. I would never buy such a unit, unless I'm using an i5 and I just want to run the fans at low rpm. There is the Fractal Design 360 (also Asetek) with 2000rpm fans, which is better. I think the question nowadays is that Intel is back with solder, then the tests might vary a bit, but water cooling still looks a better option for performance. The 3-5ºC gain is pretty good in my opinion. Five degrees is like a mile in cooling. On YouTube there are several tests with 12cm air coolers performing better than 240 / 360 AIOs. I'm not sure what these people are doing, but something is wrong with those tests. In general they are all phony. Plus, these tests need to be made with the same thermal paste. Some of the OEM thermal paste will hinder the performance. -- #15 · Sep 29, 2019 H150i and any other not Platinum Corsair AiO uses horrible garbage known as SP series fan. They're atrocious. Plats uses ML series, I believe there is one unit that uses ML too. And I have yet to see a mainstream AiO that is economically acceptable, while they still can't manage to outperform top notch air coolers by more than 4C, except for some less known units. #16 · Sep 29, 2019 (Edited)

Like I said, 5ºC in cooling is like getting a bad beating. You can separate different category of coolers by 2-3ºC. Above that, the cooler below is getting a beating in my opinion. *EDIT: those reviews with a Hyper 212X above water coolers or one unit 10ºC cooler than a slightly inferior product (like the review of the Hyper 212 vs Hyper T4) are just wrong. -- 1 Reply #19 · Sep 29, 2019 Well i have a NH-U12A with a 3800X temps are preaty ok i gess it tops out at 84cº with ambient temp of 26cº ,while gaming i see no more then 71cº. Now i do have a full custom loop from EK in a box from previous build i was going to use it while i waited for new tubbing to arrive, but from what ive been reading it probably isnt worth the time to gain 5cº, also iam using all case fans from noctua now dam thing is wisper quiet i think my waterpump made more noise then my entire system on idle ofc. #21 · Sep 29, 2019 to answer the OP it is not worth it in terms of temps but maybe you want to swap cases or have different ram or can't fit a GPU then it would be worth it to swap to an AIO or go custom loop.
