The Easy Intel CPU Performance Upgrade

Your PC will run cooler and quieter when you replace your CPU’s standard heatsink with a Hydro Series H55.

Installation is straightforward: if you can get to the back of your PC’s motherboard, you can install an H55. All you’ll need is a screwdriver.

The compact components and flexible tubing make Hydro Series H55 easy to install even if you’re cramped for space. It allows you to improve your CPU’s cooling efficiency even in most compact cases — as long as your case has a 120mm fan mount near the CPU, H55 will probably fit.

Completely self-contained

Hydro Series H55 comes pre-filled, and never needs refilling or priming.

Tool-free mounting bracket kit

The modular design makes installation simpler, and it’s compatible with Intel and AMD processors.

Low-noise, low-speed 120mm fan

The low speed and wide diameter reduces noise levels over the smaller, faster fans used on stock CPU coolers. The three-pin connector is compatible with fan controllers.

Low permeability rubber tooling

Minimal coolant evaporation helps ensure long life, and the resilient rubber offers both high flexibility and excellent leak protection.

Low-profile pump

The pump unit provides high-speed circulation without taking a lot of space. This makes installation easier, and helps improve your case’s airflow.

Latest generation micro-fin copper cold plate with pre-applied thermal compound

Copper has excellent thermal transfer characteristics, and the fin design is optimized for efficient heat exchange.

Low-profile black aluminum heat exchanger

The low-profile design reduces the airflow requirement, which helps make H55 quieter. The small size also allows for easier installation and improved compatibility, and the black finish looks great.

Customers like the cooling of the electronic component fan. They mention that the chip has never throttled, the temps didn't move much, and the CPU has never exceeded 41C even under heavy use. The supplied fan is actually very good, and it makes a clicking sound. Customers also like that they can check their temperatures almost everywhere from the software set curves.

Customers are mixed about the size of the CPU cooler. Some mention that it fits nicely in the single fan space of their desktop, while others say that it's too big to fit at the top. However, some say the unit is attractive and small. Overall, the opinions are mixed, and it'd be best to read the reviews carefully before making a purchase.

Highly recommended budget cooler. See notes on radiator!
Use CaseI run over two dozen IP cameras in my home setup and was maxing out my 7700K (even overclocked) in my Blue Iris NVR PC. It was time for an upgrade, so I settled on a i7-8086K. The CPU doesn't come with a cooling solution, and since this particular PC lives in a closet, I figured I'd go for something quiet. The case is on the smaller side (while still accepting a full-ATX board), and has accomodations for both 120x120mm and 240x120mm radiators. Aside from wanting something quiet, I needed something inexpensive, easy to install in a smaller case, with a little thermal overhead for pushing the TDP out to 180W+ (if necessary).Packaging/SetupThe item arrived in an Amazon outer box, with the inner box being a Corsair retail package. Inside, the waterblock and radiator are adequately protected. Since the setup is a maintenance-free, non-user servicable closed loop, everything is already connected. If you were wanting to use the watercooling grommets through your PC's case, this is not the setup for you. If you want nice, quick-connect fittings, and large ID tubing, you probably just need to roll your own setup. As it is, the combined pump and waterblock unit is attractive and small. The tubing is TINY. The radiator looks adequate, but small. The fans, in a push-pull setup on either side of the radiator look like they're overkill for the rest of the system. The fittings for the tubing swivel, which makes it easier to place the radiator wherever it will work best, and the waterblock in whatever orientation causes the least binding.The only real work to be done, for LGA 1151 anyway, is to put the motherboard backplate on, attach the proper standoffs, and then put on the mounting block. There is pre-applied TIM on the waterblock. It's easy enough to remove if you think you have something better. I took it off just to measure the flatness of the waterblock (it was 8/10, but I wet sanded it to 9.5/10). The mounting bracket for the LGA 1151 essentially acts as a spring, so there's not much that can go wrong. I can't really say I like the fan mounting method... essentially, you use machine screws and washers to attach the fans directly to the radiator. Presumably, attach the screws (on one side) through the case. As thin as the aluminum on the radiator is, I would really prefer it if the screws were longer and went all the way through the fan-radiator-fan sandwich; I wouldn't worry about inadvertently tearing it up by accident. The radiator CORE is 120x120mm, but the full unit is not square, as the fittings are on one side and the loopback aluminum tubing is on the other side. Depending on the size of your case, that may limit you to two (instead of four) orientation choices.PerformancePowering up the system was uneventful. There are PWM headers for the fans, a header for the pump speed (?), and a SATA power header for the pump. The pump speed header may be a Hall-effect sensor of some sort, but the general idea is the same as when you have a failure on your CPU HSF. The system is very quiet, and kept temperatures in check. Since it wasn't really my build was about, I didn't try to see what the limit was, but I did get a completely stable (100% load for 4 hours) 400Mhz overclock. Temperatures only increased a little over stock.ConclusionI bought this system with a tight space and monetary budget in mind. I feel like I got a good value for what I spent. Since I just recently started using this, I can't really speak to the longevity of the pump over time, but my previous experience with Corsair watercooling all-in-ones has all been positive. Highly recommended.

Zum Produkt
Ich hatte keine propleme mit dem Produkt
Es kam gut verpackt an und original verschweißt keine propleme wie die Vorgängerrezensionen

Die Installation gestaltet sich angenehm einfach
Die brackets tauschen die einfach nur eingedreht werden die Schrauben mit den Klammern draufdrehen und aufsetzten festziehen und das war's im Prinzip auch schon der Wärmetauscher macht einen guten soliden Eindruck
Die Fans sind so mittelprächtig würde ich ich sagen aber für den Preis durchaus in Ordnung

Da ich mein uefi Fan controll auf turbo gestellt habe sind die Lüfter etwas lauter da sie schon frühzeitig etwas höher drehen
Der Geräuschpegel stört mich aber weniger jedoch legen viele da ja sehr viel Wert trauf
Ich sitze aber zu 95 % sowieso mit Headset vorm PC weswegen ich davon nichts mitbekomme

Ich habe einen ryzen 9 3900x
12 Kerner der mit den mitgelieferten AMD wrait Prism zwar schön aussah ich aber teilweise knapp an der Grenze zum Throttling befand mit teilweise 97 Grad

Mit der h75 sind meine Temperaturen nun bei max 71 Grad unter Prime

Als Wärmeleitpaste habe ich Arctic mx4
Diese leistet gute Dienste und ist einfach in der Handhabung

Ich kann den Kühler jedem empfehlen der eine Budget Kühlung benötigt die ausreichend Kühlung bringt und ein etwas Lauterer Betrieb nicht stört

Ich bin voll zufrieden damit und würde sie mir jederzeit wieder kaufen

Bei intell wird noch eine Backplate Änderung notwendig sein die mitgeliefert wird da ich allerdings keine Intel CPU besitze könnte ich diese Schritte nie ausführen würde aber davon ausgehen das der Einbauprozess nicht groß umständlicher ist
