The most reliable way to identify your CPU cooler is checking the physical label or printed model name directly on the cooler itself, usually visible on the fan housing, heatsink, or pump block. Software tools sometimes report cooler information, but this isn’t universal, making a direct physical check the most dependable method.
- The physical label on the cooler is the most reliable identification method.
- Software detection of coolers is inconsistent and not always available.
- Your original purchase receipt or prebuilt spec sheet can also confirm the model.
- Knowing your cooler model helps find compatible replacement parts or fans.
Method 1: Check the Physical Label
- Power off and unplug the PC, then open the case.
- Look at the fan housing, heatsink side, or AIO pump block for a printed brand name and model number.
- For tower air coolers, the model is often printed on a sticker on the top fan or side of the heatsink fins.
- For AIO liquid coolers, check the pump block’s top cover, which usually displays the brand and model prominently.
Method 2: Check Your Purchase Records
If you built your own PC, check your original order history or a saved PCPartPicker parts list, which will show exactly which cooler you selected. For a prebuilt system, check the original spec sheet or order confirmation.
Method 3: Software Detection (Limited)
Monitoring tools like HWiNFO sometimes report cooler or fan controller information, particularly for coolers with built-in digital displays or advanced fan controllers, but this isn’t consistent across all cooler brands and models, making it a supplementary check rather than a primary method.
Why Knowing Your Cooler Model Matters
- Finding replacement fans if one fails, since specific fan sizes and mounting patterns vary between coolers
- Confirming compatibility when upgrading to a new CPU with a different socket, per how to install a CPU cooler
- Checking manufacturer support pages for firmware updates on coolers with digital displays or RGB software
Checking Cooler Compatibility for a New CPU
If you’re upgrading your CPU to a different socket type, following how to choose PC parts that work together, check whether your current cooler’s included mounting brackets support the new socket, since many coolers offer free replacement brackets from the manufacturer for newer socket generations.
Tip: take a photo of your cooler’s label once you find it, since case clutter and cable routing can make it hard to check again later without significant disassembly.

Frequently Asked Questions
Can software tell me what CPU cooler I have?
Sometimes, particularly for coolers with digital displays, but this isn’t universal. The physical label remains the most reliable check.
Where is the model number printed on an AIO cooler?
Usually on the top cover of the pump block, which typically displays the brand and model prominently.
Why would I need to know my cooler’s exact model?
To find replacement fans, confirm socket compatibility for a CPU upgrade, or check for firmware updates on digital-display coolers.
Can I check my cooler model from my original purchase records?
Yes, a saved PCPartPicker list or order confirmation for a prebuilt system will show exactly which cooler was included.
