If you searched for “kpacific air cooler pc 100” hoping to find a PCcooler-branded computer cooling part, I want to clear up the confusion right away before you buy the wrong thing. The Kpacific PC100 is not a CPU cooler, a case fan, or anything you install inside a desktop tower. It is a portable evaporative air cooler, sometimes called a swamp cooler, made by the Malaysian brand Kpacific for cooling a room, not a processor. The similar-sounding name is a coincidence, since PCcooler (sold as PCCOOLER or CPS) is a completely different company that makes air and liquid CPU coolers, fans, and PC cases.
| Type | Portable evaporative air cooler |
| Cooling Method | Water-soaked evaporative cooling pad |
| Ice Compartment | Yes, optional ice chamber for extra cooling |
| Fan Speeds | Multiple speeds with oscillation |
| Mobility | Caster wheels for room-to-room use |
| Filter | Washable dust filter, replaceable cooling pad |
| Best Suited For | Small to medium rooms in dry or moderate humidity |
| Power Draw | Significantly lower than compressor-based AC units |
I ran into the exact same mix-up a while back when I was shopping for a cooler for a small home office in Malaysia during a heat wave. I typed “air cooler PC100” into a search bar expecting a PC cooling fan and instead landed on listings for a floor-standing evaporative cooler. Once I understood what the Kpacific PC100 actually was, I realized it was still worth covering here, because plenty of readers land on the same search result and want an honest answer instead of a page that pretends the mix-up does not exist.
What the Kpacific PC100 actually is
The Kpacific PC100 is a portable evaporative air cooler built for home and light commercial spaces. Instead of using a compressor and refrigerant like a split-unit air conditioner, it pulls warm air through a water-soaked cooling pad. As the water evaporates, it absorbs heat from the air, and a fan pushes the cooled, slightly humidified air back into the room. This is the same basic principle behind a desert cooler or swamp cooler, and it works best in dry or moderately humid climates rather than in a closed, already humid room.
- Large airflow rating designed to cool a small to medium room quickly
- Water tank plus ice compartment option for extra cooling on hot days
- Multiple fan speeds and oscillation for even air distribution
- Caster wheels so it can be rolled between rooms
- Washable dust filter and a cooling pad that needs periodic replacement
How it is different from an air conditioner
An evaporative cooler like the PC100 uses far less electricity than a window or split air conditioner because it has no compressor. That makes it cheap to run, but it also means it will never get a room as cold as true air conditioning, and performance drops in humid weather since the air is already holding a lot of moisture. It is best treated as a large, efficient fan that also lowers the temperature a few degrees, not a full AC replacement.
Setting it up correctly
Getting good performance out of the PC100 mostly comes down to placement and water management. A few things I learned from using a similar evaporative unit myself:
- Fill the tank with clean water, and add ice cubes to the ice compartment if your unit has one for an extra cooling boost.
- Position the cooler near an open window or door so it can draw in fresh air rather than recirculating the same humid air.
- Let the cooling pad soak for a few minutes before switching to a high fan speed, otherwise you are just moving warm air around.
- Clean the water tank weekly to stop algae and odor from building up, especially in tropical climates.
- Replace or rinse the cooling pad every season, since a clogged pad cuts airflow and cooling power noticeably.
Common issues and quick fixes
Most complaints about evaporative coolers like the PC100 come down to a handful of predictable problems rather than an actual defect.
- Weak cooling: usually a dry or clogged cooling pad, or the unit is running in a sealed room with no fresh air coming in.
- Musty smell: stagnant water left in the tank for too long; drain and clean it, then let the unit dry out before refilling.
- Water leaking from the base: check that the unit is sitting level and that the drain plug is fully seated.
- Noisy operation: the fan motor may need the dust filter cleaned, or the unit needs to sit on a level, stable floor.
If you have already tried these steps and the unit still is not cooling, it is worth checking the manufacturer’s support page for your specific model, since Kpacific and similar evaporative cooler brands publish troubleshooting guides and replacement pad part numbers for their lineup.
Should you actually buy this instead of a PCcooler product
If what you really wanted was a CPU cooler for a gaming PC or workstation, the Kpacific PC100 will not help you at all, and you should look at PCcooler’s actual lineup, such as air coolers or AIO liquid coolers, on PCcooler’s official product pages. But if you searched for a room cooler and just got confused by the similar model number, the PC100 is a reasonable budget option for a bedroom, home office, or small shop in a hot, relatively dry climate, and it is worth comparing against other evaporative coolers before you decide, using a resource like the general overview of how evaporative cooling works to set realistic expectations.
Frequently asked questions
Is the Kpacific PC100 related to PCcooler computer parts?
No. Kpacific is a separate air-conditioning and evaporative cooler brand. PCcooler, also sold as PCCOOLER or CPS, makes CPU coolers, case fans, and PC cases. The matching “PC100” style naming is a coincidence.
Can the PC100 cool an entire house?
Not effectively. It is designed for a single room or a small open area. For a whole house, you would need either multiple units, good cross-ventilation, or a proper central cooling system.
Does it work well in humid weather?
Evaporative cooling loses effectiveness as humidity rises, since the air can hold less additional moisture. In a tropical, humid climate you will notice less temperature drop than in a dry climate.
How often should I change the water?
Daily use is best, or every two to three days at most, to avoid stagnant water, odor, and mosquito breeding in the tank.
Final thoughts
The keyword mix-up between PCcooler PC computer parts and the Kpacific PC100 evaporative room cooler is an easy one to make, since the model numbers look almost identical out of context. Once you know the PC100 is actually a room cooling appliance, you can decide whether it fits your needs, or whether you should be shopping PCcooler’s actual CPU cooler catalog instead. Either way, matching the right product to the right job will save you a return shipment and a lot of frustration.
