Not all those who buy better CPU coolers overclock. This is in reference to Cooler Master Hyper 103 CPU air cooler. A CPU cooler with 3x copper heatpipes and a 92mm CPU cooler with a total height of 5.5 inches.
As always, we’ll see how good it performs, and if it provides some cooling for minor overclocks.
Cooler Master has put a picture of the CPU cooler on the front and the right side so that the user can get a good idea about the cooler. Additionally, the dimension along with the illustrations are given at the back to give a good idea of how big this CPU cooler is. The specification is mentioned towards the left.
The mounting system is kept inside a box while the CPU cooler is resting on a three-sided foam with the fan facing towards the open side.
Cooler Master provides all the mounting required for Intel LGA 775, 115x, LGA 2011/2011-V3 and AMD platforms. Cooler Master bundled this LGA 115x/AMD combo backplate where you can switch sides depending on which mounting holes you’re using. I do wish that the backplate was of Intel platform only since usually AMD motherboards have a backplate by default. Certain mini-ITX motherboards may have some obstruction which would block it from being installed.
Additionally, Cooler Master provides a small syringe of thermal paste, making it as a complete package.

Cooler Master really needs to mention ideal TDP rating for this CPU cooler in its specs with respective socket processor types.
Cooler Master Hyper 103 is a pretty compact design for a U-type CPU cooler. While it’s not a low-profile CPU cooler. The CPU cooler is 5.5 inch/138 mm tall and 4.3″/108 mm wide. Cooler Master Hyper 103 CPU cooler is very lightweight. The CPU fan is a 4-pin 92mm sleeve bearing PWM fan A9025-22RB-4BP-F1 pre-installed with plastic clips. There are 3x copper heatpipes each with Ø 6mm with direct heatpipe contact on the base. There are 40 stacks of aluminum fins. The lifespan of the fan is rated for 40,000 hours, which is equivalent of 1,667 days- that’s a bit more than 4 years and 5 months.
The 92mm fan clamps are easy to remove and re-mount. I am not sure why does Cooler Master have a separate label with a ‘wheelie bin’ logo and ‘Warranty void if removed’ on the fan’s wiring- or any tag at all. Is that even required??
The fans have four adhesive pads which are pressed against the sinks to ensure it prevents vibration. You can swap the 92mm fans but peel off this adhesive-backed pads which allow you to remove the screws and detach the clamps.
The design of the heatsink shows that there’s an offset and asymmetrical placement so that it looks ‘center’ with the 92 x 92 x 25 mm fan. This design helps to keep the 92 mm looks ‘compact’. Unfortunately, you cannot mount a second fan even if you wanted to. There’s a small passive sink type design below the aluminum stacks.
Cooler Master mentioned in its product page that the Hyper 103 CPU cooler uses a patented air-guide technology which in a nutshell is the means to direct airflow and using a series of dimples to route the airflow through the heatpipes. There’s also X-vent which has cross-shaped ventilation around each heatpipe to created controlled vortices.
We’ll see how the CPU cooler performs overall.
Cooler Master Hyper 103 is a 92mm fan-based CPU air cooler so one would safely assume that it wouldn’t have any clearance issue. It stays true to that, but my concern is the universal backplate.
While there isn’t any issue in regards to Intel mounting holes, the AMD’s backplate mounting holes is way too close to one of the spring-loaded screws that secures the heatsink from the other side. With Gigabyte Z97X-Gaming GT, the single upper part of the heatsink covers the VRMs, the MOSFETs and another chip (for the older users, placed typically where Northbridge is usually placed). I am also a little concerned especially in the case of a certain mini-ITX motherboard that may have something that would potentially have a contact with the AMD mounts. With this motherboard, there’s a hairline size space between them, but I decided to tape the AMD bracket to ensure the space between it is maintained.
In any case, I feel that providing AMD backplate mounts with a CPU cooler is redundant. All AMD chipset motherboards are with a solid metal backplate (Or plastic backplate with metal threaded mounts, like how BIOSTAR did) that does the job even for a dual tower CPU coolers. The CPU cooler manufacturers simply need to provide the screws with the same threads, length and thickness.
Installing with this LGA bracket is a little different compared to the plastic variant that Cooler Master Hyper D92 uses. Once the backplate is mounted, you need to install the flat headed screws on the mounting holes and then slip in the plastic washer. The washer helps not only to keep the screws in place but also prevent the metal part of the backplate from touching the PCB of the motherboard.
Now, typically one will slip on the four pieces of spacers on all four sides so that the brackets will stay in place. Instead, the mounting screws has a groove where the brackets rest over it. Okay…
The brackets are installed on the two sides of the heatsink base with two pre-drilled and threaded holes with a couple of smaller size Phillips head flat screws. The overall experience of installing the mounting brackets is decent. I would have preferred the plastic in CM Hyper D92 variant whose only complaint I had was that the bracket’s heatsink mounting holes should have been threaded. This is a very light CPU cooler, which weighs in at 580 gms.
The CPU cooler only allows one fan to be installed. As you can see above, the CPU cooler is designed in a way that heatsink and the major part of the copper heatpipes are off-set from the center, but it doesn’t look when you clip the fans on it.
Irrespective of the mounting position, there’s plenty of clearance around, as one will expect to see in such CPU air coolers.
I am not sure why Cooler Master has a couple of labels on the fan’s wiring, with one of them voids the warranty if removed. It just doesn’t make any sense. But the plastic fan clips is good. Easy to remove. Easy to clip on.
It gives me great pleasure every time I put up a review. It’s always good to appreciate the support that the manufacturers give from time-to-time to review their own products and others on behalf of the readers. Thanks to companies such as Asus, Gigabyte, Kingston, WD and Coolermaster who give me hardware support by updating my test rig no strings attached. Thumbs up to these guys! I would like to thank

The fan is set on full speed. No LNA adapters were used for testing to simulate maximum performance. Used Noctua NT-H1 thermal paste (Pea Method) System kept on idle for 30 minutes before testing to record minimum temperatures.The test is done in closed case setup with case’s ambient temperature (recorded via Temperature probe) of 37 degrees with erratic +/- 1-2 degrees fluctuation.

CM Hyper 103 crossed 93-degrees Celcius on load while the other 95mm stayed well within 90°C.
If you’re not overclocking and you need a cost-effective CPU cooler that does a much better job than the stock cooler, Cooler Master Hyper 103 is something you can take a look at. You’re getting a small thermal paste syringe and everything you need to mount the CPU cooler. The backplate is good enough, but I would be more comfortable if Cooler Master reconsiders the universal backplate idea. Every AMD motherboards have a good backplate and for 500+ 80 (fan) gms. heavy CPU cooler, it’s enough.
If you plan on overclocking, there are better alternatives. Makes sense that such coolers do not have a second CPU fan mounts.
The A9025-22RB-4BP-F1 PWN fan has blue LEDs on it, for those who are interested to know. With full speed preset in the BIOS reflecting the fan speed of 1506RPM, its reasonably quiet in a closed case setup. The plastic clamps can be removed to be swapped with another 92mm, but make sure to remove the adhesive-based rubber pads.
There is a minor issue.
Coolermaster Hyper D92 ended up requiring the bit more thermal paste than I would use. That’s likely because of the non-flat surface. One would speculate that direct heatpipe may have some inconsistent flat. But judging by the amount of thermal paste deposited in the grooves between the copper heatpipe contact, it seems uneven.
Most regular users will say that spreading the thermal paste is a much better choice for direct heatpipe-made heatsinks. True, but the heat and pressure once installed will cause the thermal paste to spread further. Spreading the thermal paste over the IHS of the processor and keeping it thin enough is tricky. Maybe a pre-applied solution is a better idea. Still, its not a problem. It did spread the thermal paste on all four corners.
For its class and price, CM Hyper 103 does a good job. But if it wasn’t for the universal backplate and the uneven base, a gold standard would be a no-brainer. Not having a second fan for its class is not a con, but it would be nice to see a true low-profile CPU cooler from Cooler Master with the same performance. Of course, this would be a wishful thinking considering a very well built low-profile CPU cooler like Noctua L9x65 doesn’t match Hyper 103 especially on load, but it did perform significantly better. You can call it as a ‘necessary trade-off’.
This wouldn’t fit in cases that have low height clearance for slim-profile/ small form factor cases like Coolermaster Elite 130, but that’s where the low-profile Noctua NH-L9x65 CPU air cooler steps in. CM should also reconsider not having the recycle and warranty void label on the fan’s wire.
There’s also another concern that Cooler Master does not have TDP rating in its website, product sheet or in its specification. The TDP for Core i7-4790K is 88w, in case somebody is looking for a reference.
