Inter-Tech Elektronik Handels GmbH is a company based in Germany and was founded in 1996. Since then, the main focus has been on the Europe-wide distribution of OEM and retail hardware for PC systems. Originally, the portfolio mainly comprised PC cases and power supply units. However, this has since been expanded to include numerous divisions such as fans, peripherals, hard disk enclosures and adapters. In August 2024, Inter-Tech once again expanded its portfolio in the area of CPU coolers. One of the new products is the Inter-Tech 4P90 Pro Bulk air cooler, which we are testing today.
The Inter-Tech 4P90 Pro Bulk is a compact tower cooler with a 92 mm fan, four copper heatpipes with Heatpipe Direct Touch and, compared to the “Non-Pro” version, a more solid mounting system with high socket compatibility. The Inter-Tech 4P90 Pro Bulk starts at € 22.38 *.
Note: The Inter-Tech 4P90 Pro Bulk was tested in the bulk version, which is usually intended for system integrators. This means that the CPU cooler is delivered in unprinted packaging and without assembly information.

Packaging & scope of delivery
Inter-Tech packs the 4P90 Pro Bulk in neutral brown cardboard packaging. Only a small label on the top states the product name and no technical data is printed on the box. Inside, protected by foam, we find the heat sink with pre-installed fan as well as all mounting materials and a bag of thermal paste. No assembly instructions were included with the bulk version.
Design & finish
At first glance, there are very few visual differences between the 4P90 Bulk and the 4P90 Pro Bulk. At second glance, however, you can see that the heat sink consists of 38 instead of 36 black-painted aluminum fins. The four heatpipes with a diameter of six millimeters and the use of heatpipe direct touch technology remain the same. However, the heat sink is slightly offset to the rear. The “Pro” version does not have a cover cap for the top or ARGB lighting either.
The Inter-Tech 4P90 Pro Bulk weighs 325 grams and is therefore lighter than the “Non-Pro” version. According to the website, the CPU cooler measures 135 x 97 x 73 mm (H x W x D) and is therefore identical in size to the 4P90 Bulk. Unfortunately, this information is not true. More on this in a moment.
In terms of the general workmanship, we could not find any anomalies. There were no bent slats or dents and all components were painted cleanly. The look and feel of the Inter-Tech 4P90 Pro Bulk are of course not comparable with more expensive CPU coolers due to its price range.
The fan is in no way inferior to the heatsink in terms of simplicity. It consists of a black fan frame and a black rotor blade with seven blades. Inter-Tech specifies a speed range of 800 to 2000 revolutions per minute and the connection is made via a 4-pin PWM connector. There are no rubberized corners and it is attached to the heat sink using simple but black-painted metal clips.
Finally, a small comparison of the Inter-Tech 4P90 Bulk and 4P90 Pro Bulk. Unlike the data sheet, the “Pro” version has different dimensions and is slightly smaller. Inter-Tech should revise its website here.
Inter-Tech 4P90 Pro BULK Test: Assembly
For the review, a test system is used which is mounted on a benchtable. This allows us to rule out factors such as heat build-up in the case. The test system consists of the following components.
- AMD Ryzen 5 1400 @ 3.8 GHz at 1.175V*
- ASUS TUF Gaming B550M-Plus*
- Crucial Ballistix Sport LT gray 32 GB DDR4-3000*
- TeamGroup T-Create Classic PCIe 4.0 DL*
- Gigabyte AORUS GTX 1060 6G*
- LC-Power LC550 V2.31 Platinum Series 550W*
In the “Pro” version, Inter-Tech implements a mounting system that provides a fixed screw connection to the mainboard. First, the plastic brackets of the AMD retention module must be removed and four spacers placed on the lugs of the backplate instead. Next, we had to screw two black-painted retaining brackets to the spacers and the mainboard.
The mounting brackets used have various holes so that they can also be used with any Intel socket. Only the supplied backplate has to be placed on the back of the mainboard.
If you have already installed a CPU cooler with a similar mounting system, you don’t have to learn anything new with the Inter-Tech 4P90 Pro Bulk. However, if you are installing a CPU cooler of this type for the first time, you will probably miss the instructions sorely. Even though all components are individually packaged and labeled “AMD” or “Intel”, assembly could be difficult for a newcomer.
Compared to the Inter-Tech 4P90 Bulk, the assembly of the “Pro” version takes a little longer, but the overall result is more stable and better suited for transporting a system. This could make more sense for use by system integrators.
Cooling capacity and volume
As already shown in the previous chapter, we use an AM4 system based on the Ryzen 5 1400 and the ASUS TUF Gaming B550M-Plus as test hardware. The Ryzen runs overclocked to 3.8 GHz at 1.175 V CPU voltage. To heat up the processor, it was loaded with Prime95 (Small FFTs) for 30 minutes. The temperature of the CPU was then read out with the CPUID hardware monitor and the room temperature was always around 20 °C during the measurements.

As can be seen from the table and the diagram, the CPU of our test system reaches a maximum of 67.0 °C (at minimum speed), 59.60 °C (at 50% PWM fan speed) and 53.10 °C (at 100% PWM fan speed) under full load. This puts it slightly behind the “Non-Pro” version in our comparison and only slightly ahead of it at full fan speed. If measurement tolerances are included in the evaluation, then it can be said that the cooling performance is identical.
Despite a maximum speed of 2000 revolutions per minute, the Inter-Tech 4P90 Pro Bulk also remains relatively inconspicuous in terms of noise, but of course not inaudible. If the fan is set to below 1500 revolutions per minute, the fan can hardly be heard in a normal system.
Conclusion of the Inter-Tech 4P90 Pro Bulk test
There are differences between the Inter-Tech 4P90 Pro and the 4P90 in terms of installation, dimensions and weight. In terms of cooling performance, the CPU coolers operate at a very similar level and the fan should also be identical, with the exception of the type plate.
The conclusion is therefore similar to that of the Inter-Tech 4P90 Bulk. The Inter-Tech 4P90 Pro Bulk is a simple tower cooler with a black finish, which is a good replacement for any boxed cooler and is also suitable for narrow office cases thanks to its compact dimensions. It even remains quite quiet up to a certain speed. Despite a different but very solid mounting system with screws, the Inter-Tech 4P90 Pro Bulk also offers very high compatibility with many AMD and Intel sockets.
On the negative side, we again noticed the lack of assembly instructions and the fact that the cooling performance of the “Pro” version is no better than that of the “Non-Pro” version. This could be misleading if the manufacturer does not clearly describe on its website where the differences between the two versions actually lie. In addition, not all of the technical information on the manufacturer’s website was correct at the time of the review.
Whether you ultimately opt for the Inter-Tech 4P90 Bulk or 4P90 Pro Bulk therefore depends solely on the desired mounting system. The “Non-Pro” version is quicker to install, while the “Pro” version is screwed on completely and looks more solid. In any case, both CPU coolers are a sensible replacement for a boxed cooler. The purchase price of the Inter-Tech 4P90 Pro Bulk from € 22.38 * is very close to the “Non-Pro” version. However, significantly more powerful tower coolers with 120 mm fans are now similarly expensive.

The Inter-Tech 4P90 Pro Bulk is a compact and simply stylish tower cooler with a black design and a solid mounting system, which is well suited as a replacement for the boxed cooler. However, the bulk version comes without mounting instructions and the "Pro" designation only refers to the mounting system and not to the cooling capacity.
