How we chose coolers for the FX-8320
This list is research-based, built from manufacturer pages and our November 2026 Amazon US data rather than our own testing. Wikipedia’s FX list puts the FX-8320 on socket AM3+ at 125W TDP, launched in 2012, so every pick needed both AM3+ mounting hardware and enough capacity for a 125W chip that many owners overclock.
That rule removed most popular coolers. AM4’s mounting holes sit 54x90mm apart, while older AMD sockets used 48x96mm, so coolers that ship only AM4 and AM5 hardware do not bolt onto an AM3+ board. We searched the Amazon data for listings that still name AM3 or AM3+ and kept only branded models.
That left fewer choices than usual, so this list has six coolers rather than seven or eight. We excluded unbranded listings whose specs come only from a product title, and we flagged where AM3+ support comes from a manufacturer page rather than the Amazon listing.
The best AMD FX-8320 coolers in detail
Each pick below covers who it suits, the specs we could verify, how AM3+ support is documented, pros and cons, and a buy or skip rule. Liquid coolers dominate the list because they are the main current products that still include AM3+ brackets, not because the FX-8320 strictly needs liquid cooling.
Cooler Master MasterLiquid ML240L RGB V2
The ML240L RGB V2 is the best overall pick for an FX-8320. It is a 240mm AIO with a dual-chamber pump and two 120mm fans, and its Amazon listing still names AM3+ and AM3, which makes it one of the most widely reviewed coolers you can still mount on an FX board.
The Amazon listing gives a 277×119.6×27.2mm radiator, a third-generation dual-chamber pump, two SickleFlow 120mm ARGB PWM fans, EPDM tubing, and AMD support for AM4, AM3+, AM3, AM2+, AM2, FM2+, FM2 and FM1, plus Intel sockets; the title also lists AM5. It was listed around $90 on Amazon US with a 4.6 out of 5 rating from about 9,610 ratings as of November 2026.
- Pros: AM3+ named in the listing; very large rating base; 240mm radiator suits a 125W chip.
- Cons: about double the price of the Frozen Notte 240; LGA 1700 users need a separate kit if they move to Intel later.
Buy if you want a proven 240mm AIO that mounts on AM3+ today and AM4 or AM5 later. Skip if price is the deciding factor.
Thermalright Frozen Notte 240 Black ARGB V2
The Frozen Notte 240 Black ARGB V2 is the value 240mm AIO for an FX-8320. Thermalright’s product page lists AM3(+) among its AMD sockets and backs the cooler with a five-year warranty, which is reassuring when you are putting a budget AIO on an older system.
Thermalright lists TL-E12B-S 120mm fans, a pump rated to 5300rpm, a five-year warranty and support for AMD AM4, AM5, AM3(+) and FM plus Intel 115x, 1200, 1700, 1851, 2011 and 2066. The Amazon listing gives two fans at 2000rpm with 72.37 CFM and 27.7 dBA or less, but its socket list omits AM3, so confirm the AMD bracket with the seller. It was listed around $47 with a 4.6 out of 5 rating from about 467 ratings as of November 2026.
- Pros: low price; five-year warranty; AM3(+) on the manufacturer page.
- Cons: Amazon listing does not mention AM3+; fast fans can be loud at full speed.
Buy if you want an affordable 240mm AIO with a long warranty for your FX-8320. Skip if you need AM3+ support confirmed on the exact listing you order from.
Cooler Master MasterLiquid 360L Core ARGB
The 360L Core ARGB is the pick for FX-8320 owners who overclock hard. A 360mm radiator gives the most surface area in this list, and Cooler Master’s own spec page still lists AM3+ and AM3, so you get manufacturer-confirmed mounting for an older AMD board.
Cooler Master lists a 394×119.6×27.2mm aluminum radiator, three 120mm ARGB fans at 650 to 1750rpm with 71.93 CFM and 27.2 dBA, a three-year warranty, and support for AMD AM5, AM4, AM3+, AM3, AM2+, AM2, FM2+, FM2 and FM1 plus Intel LGA 1851, 1700, 1200 and 115x. It was listed around $88 on Amazon US with a 4.5 out of 5 rating from about 840 ratings as of November 2026.
- Pros: largest radiator here; AM3+ confirmed by the manufacturer; reusable on AM5.
- Cons: needs a 360mm radiator mount, which many older cases lack; costs about the same as the ML240L.
Buy if your case takes a 360mm radiator and you push the FX-8320’s clocks. Skip if your case is from the AM3+ era and only fits 120mm or 240mm radiators.
Thermalright Frozen Notte 120 ARGB Black
The Frozen Notte 120 ARGB Black is the budget liquid option for FX-8320 builds in small or older cases that only have a rear 120mm mount. Its Amazon listing names AM3, AM3+ and several older AMD sockets, and it uses the board’s original AMD backplate.
The Amazon listing gives a 120mm radiator, a fan at up to 2000rpm with 72.37 CFM and 27.7 dBA, and support for AMD AM4, AM5, AM2, AM2+, AM3, AM3+, FM1, FM2 and FM2+ plus Intel 1150, 1151, 1155, 1156, 1200 and 1700, and notes that AMD installs need the motherboard’s original backplate. It was listed around $37 with a 4.4 out of 5 rating from about 977 ratings as of November 2026.
- Pros: low price; AM3+ in the listing; fits a single 120mm mount.
- Cons: a 120mm radiator has limited capacity for an overclocked 125W chip; the rating count appears shared with other colors.
Buy if your case only fits a 120mm radiator and you run the FX-8320 at or near stock. Skip if you overclock heavily.
Thermaltake TH120 ARGB Sync V2
The TH120 ARGB Sync V2 is a 120mm AIO from a major brand that still lists AM3+ and AM3. It suits FX-8320 owners who want a known name and a stated manufacturer warranty on a compact liquid cooler for a rear 120mm fan mount, which most AM3+-era cases have.
The Amazon listing gives a single 120mm fan at 500 to 2000rpm, a mirror-finish waterblock with motherboard ARGB sync, a two-year manufacturer warranty, and support for AMD AM5, AM4, AM3+, AM3, AM2+ and AM2 plus Intel LGA 1851, 1700, 1200 and 115x. It was listed around $70 on Amazon US with a 4.5 out of 5 rating from about 340 ratings as of November 2026.
- Pros: AM3+ in the listing; stated warranty; wide socket list for later reuse.
- Cons: costs nearly double the Frozen Notte 120; same 120mm radiator limit.
Buy if you want a branded 120mm AIO with clear AM3+ support. Skip if value matters most, since the Frozen Notte 120 covers the same sockets for less.
Cooler Master Hyper 212 Black Edition
The Hyper 212 Black Edition is the air option for FX-8320 owners who want to avoid a pump. Cooler Master’s spec page for the RR-212S-20PK-R1 still lists AM3+ and AM3, which is rare for a current air tower, and the single 120mm fan layout suits older mid-tower cases.
Cooler Master lists 123x77x158.8mm, four heat pipes, a 120mm fan, a two-year warranty, and support for AMD AM4, AM3+, AM3, AM2+, AM2, FM2+, FM2 and FM1 plus Intel LGA 2066, 2011-v3, 2011, 1366 and 115x. It was not in our November 2026 Amazon data, so we cannot quote a current US price or rating.
- Pros: no pump; manufacturer-confirmed AM3+ support; classic tower that fits many older cases.
- Cons: 158.8mm tall; single 120mm tower has less margin than a 240mm AIO for an overclocked 125W chip; availability not confirmed.
Buy if you prefer air cooling and can find this exact model in stock. Skip if you overclock the FX-8320 well beyond stock, where a 240mm or 360mm AIO is safer.
Buying guide for an FX-8320 cooler
Choosing a cooler for an FX-8320 is mostly a compatibility exercise: confirm AM3+ hardware first, then match capacity to how you run the chip, then check that your older case can hold the radiator or tower. Work through the points below before ordering.
Confirm AM3+ hardware, not just AMD support
Many listings say “AMD” but only include AM4 and AM5 brackets. AM4 holes are spaced 54x90mm and older AMD sockets 48x96mm, according to Wikipedia’s AM4 article, so an AM4-only cooler will not bolt onto an AM3+ board without a different bracket from the manufacturer.
Look for AM3+ or AM3 on the manufacturer page. Wikipedia also notes that coolers using AMD’s two-prong clip style can work across AM4 and older sockets, but check the cooler manual before relying on that.
Capacity for a 125W chip
Wikipedia lists the FX-8320 at 125W TDP, the same as the FX-8370, while the FX-8370E and FX-6300 are rated at 95W. A 125W chip at stock settings suits a good single tower or a 120mm AIO in a case with reasonable airflow, but that leaves little margin for overclocking or a warm room.
If you overclock, power rises well above 125W, so a 240mm or 360mm AIO gives more margin than a single tower or 120mm radiator.
Fitting coolers in older cases
Many AM3+-era cases have limited radiator support, often just a rear 120mm mount, and modest tower clearance. Check for 240mm or 360mm front or top mounts before buying a larger AIO, and measure tower clearance from the board to the side panel with a ruler.
A 2026 report on Noctua’s measurements found more than half of 100-plus cases deviated significantly from listed clearance, so leave a few millimeters spare.
Other AM3+ options worth checking
Two coolers outside our November 2026 Amazon data still list AM3(+) on their makers’ own pages, so they are worth a look if you can find stock from another retailer. Scythe’s Mugen 5 Rev.C lists AM2(+) and AM3(+) at 154.5mm tall with a one-year warranty, and ARCTIC’s Freezer 7 X manual covers AM3(+) mounting.
ARCTIC notes the Freezer 7 X fan is not PWM-controllable on AMD, and it is a small 100mm-fan cooler better suited to 95W FX chips than an overclocked FX-8320.
FAQ
These answers cover common questions from FX-8320 owners looking for a new cooler. They draw on Wikipedia’s FX and AM4 articles and the manufacturer and Amazon pages cited above, so confirm bracket contents with the seller before buying, since packaging can change between production runs.
Will an AM4 cooler fit an FX-8320 board?
Usually not. AM4 coolers that screw into a backplate use a 54x90mm pattern, while AM3+ uses 48x96mm. Some coolers using AMD’s clip-style bracket fit both, and some motherboards had both hole patterns, but check before buying rather than assuming it will fit.
The safest route is a cooler whose manufacturer page names AM3+ or AM3, like the 360L Core ARGB or Hyper 212 Black Edition.
Are the best CPU coolers for 8320 chips worth buying for an old PC?
If the system is still useful to you, yes. A 120mm AIO such as the Frozen Notte 120 costs about $37 on Amazon US as of November 2026, which is little compared with replacing the whole platform, and most picks also support AM4 or AM5, so the cooler can move to a newer build later.
If you plan to retire the PC soon, a cheap cooler that matches stock settings is the sensible buy.
Do I need liquid cooling for an FX-8320?
Not at stock settings. A good single tower with AM3+ hardware, such as the Hyper 212 Black Edition, handles a 125W chip. Liquid coolers dominate this list mainly because they are the current products that still ship AM3+ brackets, and because many FX-8320 owners overclock.
If you overclock, a 240mm or 360mm radiator gives the most headroom of the options here.
Conclusion
Buy the Cooler Master MasterLiquid ML240L RGB V2 for an FX-8320: its listing names AM3+, its 240mm radiator suits a 125W chip with overclocking headroom, and it has a very large Amazon rating base. Choose the Frozen Notte 240 only if price and its five-year warranty matter more.
