One thing to keep in mind about the Deepcool Assassin IV is that the default fans are set in a pull-pull configuration, which is rare. This makes the cooler hungry for airflow, so if you have a small case with poor ventilation, then it may not perform well. Cases that have a good positive air pressure setup (meaning more intake fans than exhaust fans) will enable the Assassin IV to perform at maximum cooling capacity.
-Air cooling a Ryzen 9 5900X (AM4 Platform), with an ASRock motherboard, RAM clearance isn’t an issue.
-Cooler is so sleek, it’s nice not to visually see a fan
-140mm & 120mm fans are nice and hidden and do a pretty good job cooling
-I’m not the person to ask about fan noise cause I care about cooling than noise.
-I’ve owned Notcua NH-D15 and BeQuiet Dark Rock Pro 4 cooler. In comparison, they’re pretty close in cooling performance. It’s hard to say which one is better as they all perform within the same range. At this point, it’s definitely in competition with the big dogs. It’s now an esthetic reason on which you’d like to get.
-Nice having an option for a more silent mode with a switch built into the cooler basically charging the RPM range.

Safe to say this cooler is amazing I would recommend this over a overpriced AIO anyday.
As far as fitment... It's a big chunky cooler, so I know other people will have the same questions I had... Does it fit with X configuration... So I'll post my configuration and go into some details. It doesn't seem to interfere on the ASUS B-450F with the top graphics card slot or the top PCI-E 1x slot, but it does hang over my ram. I have 64GB (4 sticks) of Crucial Ballistix DDR4-3200 (BL2K16G32C16U4B), so it will fit over that for those of you looking for that info. It also JUST barely fits into my Corsair Carbide 200R case... I think the "spoiler" (The silly plastic thing on top that goes level with the tops of the fans) may be may be in contact with the side cover on my case, but the case still closes fine without effort, so it may not be touching. So I will warn anyone with a 200R, this is the cooler to use, not the slightly taller Noctua (The noctua is 2mm taller according to their specs)... Which was my concern and why I bought this and not that.
Installation was pretty straight forward, the directions were well written, well drawn, and easy to follow. Everything you need to install it was included in the box, including plenty of thermal paste (More than enough for one application), a wipe to get the old thermal paste off, and a card to spread it (Which you may or may not choose to do). It was also nice that the screws included tension springs, which helps prevent over tightening (If you're truly determined you could probably overtighten it, so don't be the hulk here). The installation hardware seemed pretty well machined, and it all just fit together with no fiddling around with anything. One thing I'll mention, it's a big chonker, so it may interfere with your ability to get to your fan headers easily so I would plug in any fans BEFORE installing it (Not mentioned in the directions, but you should know). Although it doesn't hang over my fan headers, based on other fan placement in my case and where they are in my board it cuts down on clearance significantly.
The included long #2 philips magnetic screw driver was a nice touch, I would assume plenty of people don't have a long enough one to reach down between the fins and tighten those screws... So good on them. It wouldn't be the first screw driver I'd reach for, but it's very nice for a freebie.
Top reviews from other countries
Dopo aver letto una infinità di recensioni su questo Deepcool Assassin III mi sono deciso ad acquistare questa "bestia di dissipatore" (invece del solito Noctua NH-D15) per la mia seconda "workstation" basata su un Ryzen 5950X montato su una Gigabyte X570S Aero G.
Partiamo dall'inizio:
Il dissipatore arriva in una confezione ben fatta con tutte le dotazioni che ci si aspetta quando si acquista un prodotto premium di questo tipo (incluso uno splendido cacciavite con punta magnetica). La doppia torre è realizzata a regola d'arte. I materiali sono ottimi e il design minimale, sobrio ed elegante. Bella la rifinitura nera on top (con Noctua si paga a parte!).
Il montaggio è risultato molto semplice.
Per dissipatori di questo tipo non ci sono molte cose da fare per quanto riguarda il supporto alle RAM. La massima altezza supportata per i banchi è di 32mm. Se le vostre memorie hanno una altezza maggiore, dovete per forza di cose montare la prima ventola con un minimo di sbalzo. Nel mio caso ho optato per 4 banchi Corsair LPX da 16GB 3600Mhz per avere il minimo impatto.
Anche le dimensioni del dissipatore non sono da poco. E' alto 165mm (con le ventole in linea). Se come nel mio caso la prima ventola è leggermente rialzata dovete tenerne conto relativamente al case che avete a disposizione (comprate questo dissipatore solo se il vostro case vi garantisce almeno una altezza di 170mm). Personalmente avendo montato tutto in un Phanteks ENTHOO PRO non ho avuto ovviamente problemi.
Infine le prestazioni: Ottime, al livello del Noctua NH-D15. Se come nel mio caso sostituite le ventole in dotazione (che sono comunque ottime anche se un filo rumorose per delle ventole standard - non industriali) potete ottenere risultati sorprendenti.
Nel mio caso, proprio perché il rumore non è importante (ma ho bisogno di raffreddare), ho sostituite le ventole Deepcool con delle Iceberg IceGALE Xtra 140mm ottenendo un abbassamento delle temperature anche di 5/6 gradi in tutti gli scenari. Per chi non conoscesse le ventole potete leggere la mia recensione qui sul sito di Amazon. Sono delle bestie (al livello delle Noctua Industrial ma più economiche).
Per concludere questo Deepcool Assassin III è stata una sorpresa. Bello e performante. Costa ma la qualità si paga. E' un po' massiccio e impone dei limiti durante l'assemblaggio ma rispetto ad un AIO vi durerà per sempre senza crearvi nessun problema.
Un Best Buy!
Der Assassin IV hatte sich durch das doch etwas andere Design sehr abgehoben auch wenn der Preis schon im Segment von Wasserkühlungen liegt.
Die Montage war extrem einfach und durch einschub/anclippen der Lüfter viel angenehmer als die normalen Metallclips.
Die Kühlleistung für meinen Ryzen 7 5800x3D hatte ich dann mit Cinebench und dem Stresstest aus CPU-Z getestet und nach einer Stunde Laufzeit war die höchste Temperatur auf einem einzelnen Kern bei 77,8°C während dieser durchgehend mit 4,45GHz lief. Für einen Hitzkopf wie die AM4 Zen3 Prozessoren ein sehr gutes Ergebnis ist. Es wurden nur die 2 enthaltenen Lüfter genutzt, es liegt noch ein Rahmen dabei um theoretisch noch einen 3. Lüfter anzubringen.
Wenn man eine extrem gute Kühlleistung haben möchte und etwas mehr Geld in die Hand nehmen will, macht mit diesem Lüfter keinen Fehler.
Die Kühlleistung ist gut, aber nicht überragend, ein Thermalright Peerless Assassin 120 kühlt meinen Ryzen 9 5950X, der mit PBO bis zu 230W zieht, für deutlich weniger Geld genauso gut und ist dabei leiser.
Der Assassin IV hat aber auch seine Vorteile: er sieht sehr clean und edel aus und überdeckt nicht die RAM-Slots.
Montage und Verarbeitung sind ebenfalls top.
Wem aber die Optik weniger wichtig ist, wer und nur einen Top-Kühler für wenig Geld sucht, der ist hier definitiv an der falschen Stelle.
タイトル通り、この製品の価値はメモリの自由度に価値を見出せるか次第だと思う。
ファンがプル構成のためか、ケース内のエアフローを適切に管理しないと(特にアイドル時は)性能を発揮できない。
また、エアフローを整えた上でも、ASSASSIN IIIの方が冷える結果になる。
ASSASSIN IIIの方が静かで適当に扱っても冷えるので、手放しでオススメはできない。
それぞれにメリットはあるので、後継機ではなく棲み分けできる商品と考えるべき。
温度については、アイドル時はIIIより3〜5℃位高いが、負荷がかかるとIIIとの差は縮まってくる。
レスポンスは良くないが、受け止められる熱量自体は多く、それが上限に届く訳でもない。
アイドル時含め、兎に角最高に冷えるのが良いという訳で無いなら、メモリの自由度や背面ファンが不要な点も含め、決して悪くはない。
総じて商品としては良いものだが、ASSASSIN IIIの後継機としての名前で評価を落としているとは感じる。
AK500の後継か、IIIの亜種のような存在として出ていれば、評価もまた変わってきただろうか。
