Air cooler INTER-TECH 4P90 Bulk, 92 mm hydraulic fan, 125 W TDP, compatible with AM5/AM4/AM3 and LGA 1700/1200/115x/775

Inter-Tech 4P90 Bulk is a compact air cooler designed for consumer and office desktop processors. It combines a 92 mm hydraulic-bearing fan with a four-heatpipe coldplate and a black finish to deliver moderate cooling for CPUs with up to 125 W TDP. The cooler supports a wide range of modern and legacy sockets, including AM5/AM4/AM3 and multiple Intel LGA generations (1700, 1800, 1200, 115x, 775), and fits into standard PC cases where space is limited.

Advantages

The 92 mm hydraulic fan provides reliable airflow with reduced mechanical noise compared with sleeve-bearing designs, while the four heatpipes enhance heat transfer from the CPU to the fin stack. Its compact footprint (approximately 97 mm width, 73 mm depth and 135 mm height) makes the cooler suitable for smaller tower and micro-ATX enclosures. PWM support allows motherboard-based speed control for a balance between cooling performance and acoustic levels.

Suitable for

• Upgrading stock coolers on mainstream AMD and Intel desktop processors (up to 125 W TDP)
• Small or mid-tower PC builds where clearance is limited
• Office, home, and light gaming systems that require improved cooling over boxed coolers
• Systems that prioritize lower noise and compact dimensions

When it may not be suitable

This cooler is rated for up to 125 W TDP, so it may not provide adequate thermal headroom for high-end desktop CPUs or heavily overclocked processors that produce substantially more heat. Very large ATX cases with multiple high-power components or users seeking the absolute lowest CPU temperatures should consider larger tower coolers or liquid cooling solutions. Additionally, extremely tight motherboard or RAM layouts that obstruct the cooler’s profile could prevent proper installation.

Key specifications

• Type: Air cooler with 4 heatpipes
• Fan diameter: 92 mm (92 x 92 x 25 mm)
• Bearing type: Hydraulic
• Voltage: 12 V, PWM speed control supported
• Thermal Design Power (TDP): 125 W
• Approximate dimensions: 97 mm (W) x 73 mm (D) x 135 mm (H)
• Weight: 0.345 kg
• Colour: Black
• Airflow indication: ~35 CFM (typical for 92 mm hydraulic fan)

How to use

Mount the cooler onto a compatible CPU socket following the included installation manual and using the supplied mounting hardware for AMD or Intel platforms. Apply a thin, even layer of thermal paste to the CPU heatspreader before seating the cooler. Connect the 3- or 4-pin fan cable to the motherboard CPU fan header to allow PWM control where available. Verify that the cooler clears RAM modules and other components, and that case airflow is not obstructed for optimal performance.

What to consider before purchase

• Verify socket compatibility with your motherboard (AM5/AM4/AM3 or supported LGA sockets)
• Check case CPU cooler height clearance (approx. 135 mm)
• Ensure RAM and motherboard component clearance near the CPU socket
• Assess your CPU’s typical power draw—highly overclocked or HEDT CPUs may require more cooling

Recommendations

For best results, use factory-recommended thermal paste or a good-quality aftermarket paste, ensure firm and even mounting pressure, and enable PWM control in the BIOS or motherboard software to balance noise and cooling. Maintain case airflow with at least one intake and one exhaust fan to support the 4P90 Bulk’s heat dissipation.
