The best CPU coolers for i7 8700K owners rarely need to cost much. Intel rates this six-core, 12-thread chip at 95W and ships it without a cooler, so the job is finding solid capacity for gaming plus video or photo work without overspending on an older platform. These six LGA 1151 picks all cost under $100 as of November 2026.
Quick verdict
Buy the ID-COOLING FROZN A620 PRO SE for most Core i7-8700K builds: a 157mm dual tower with six heat pipes and two fans for about $30. Step up to the Phantom Spirit 120 EVO for faster fans, pick a Noctua for quiet and a six-year warranty, or the Frozen Notte 240 for liquid.

How we selected these coolers
This is a research-based roundup, not a lab test. We used Amazon US data collected on November 11, 2026, kept coolers with hundreds or thousands of ratings, and checked heights, fan setups and LGA 1151 support on manufacturer pages or listings, noting where a spec came only from a seller.
Intel lists the i7-8700K with six cores, 12 threads, a 3.7GHz base clock, a 4.7GHz maximum turbo, a 95W TDP and a 100C junction limit on FCLGA1151, and the boxed chip has no fan or heatsink. For comparison, the non-K i7-8700 is rated 65W. The K chip’s unlocked multiplier makes headroom above 95W useful.
We capped prices at about $100, since this platform is several generations old. Every pick lists LGA 1151 or LGA 115x and also LGA 1700, so it can move to a newer PC. Ranking follows verified fit and value, never commission. Prices and ratings are an Amazon US snapshot from November 2026.
Best CPU coolers for i7 8700K compared
The six picks run from best value to specific needs such as quiet running, short cases or liquid cooling. Each section covers who the cooler suits, its specs, LGA 1151 mounting and trade-offs. For most 8700K gaming and creative PCs in a mid-tower case, the first two picks cover everything you need.
ID-COOLING FROZN A620 PRO SE
The FROZN A620 PRO SE is our best overall value pick for the 8700K because it gives two towers, six heat pipes and two fans for about $30. It suits gaming plus editing builds in mid-tower cases with about 160mm or more of clearance, and buyers who want an all-black look without paying premium prices.
The Amazon listing describes six 6mm copper heat pipes, a dual-tower heatsink, two 120mm PWM fans and a 157mm total height. It lists 40mm of clearance for standard RAM, rising to 63mm with the cut-out fin, and a maximum fan noise of 27.2 dB(A). The 260W figure in the title is a seller rating.
The listing supports Intel LGA 1851, 1700, 1200 and 115X plus AM5 and AM4. We did not find a manufacturer page or warranty length to cross-check, so treat its specs as listing data. It was listed around $30 on Amazon US and rated 4.7 out of 5 from about 640 ratings as of November 2026.
- Pro: dual tower with six heat pipes for about $30
- Pro: published RAM clearance figures
- Pro: all-black finish
- Con: specs not confirmed on a manufacturer page
- Con: warranty length not verified
Buy if you want dual-tower capacity for the least money. Skip if you want manufacturer-verified specs and a known warranty, which point to the Noctua picks.
Thermalright Phantom Spirit 120 EVO
The Phantom Spirit 120 EVO suits 8700K owners who plan an all-core overclock and want more airflow than standard dual towers. It adds a seventh heat pipe and faster fans over the A620, and fits the same mid-tower cases with about 165mm of clearance or more.
The Amazon listing gives 125 x 135 x 157mm, seven fully plated heat pipes and a micro-engraved copper base. Its two TL-K12 120mm PWM fans are rated at 2,150 RPM, 69 CFM and 27 dB(A) or less. Faster fans add headroom under heavy load but will be more audible near full speed.
The listing supports Intel LGA 1700, 1200, 115x, 2011 and 2066 plus AM4 and AM5, and its title adds LGA 1851. We could not verify a manufacturer page or warranty. It was listed around $47 on Amazon US and rated 4.8 out of 5 from about 520 ratings as of November 2026.
- Pro: seven heat pipes and 2,150 RPM fans
- Pro: 4.8 Amazon rating
- Pro: wide socket list for future builds
- Con: about $17 more than the A620
- Con: specs and warranty only from the listing
Buy if you overclock the 8700K and want more airflow. Skip if you run stock clocks, where the A620 is enough for less money.
Cooler Master Hyper 212 Spectrum V3
The Hyper 212 Spectrum V3 is the budget pick for 8700K owners at stock clocks who want a quiet, documented replacement cooler. It suits gaming PCs on a tight budget and compact cases, since its narrow 73mm depth keeps memory slots clear on most boards.
Cooler Master lists 124 x 73 x 152mm dimensions, four heat pipes and one 120mm ARGB fan running from 650 to 1,750 RPM at up to 71.93 CFM and 27.2 dBA. That is adequate for a 95W chip at stock, though a single fan has less margin than the dual towers during long renders.
Cooler Master’s page lists LGA 1851, 1700, 1200, 1151, 1150, 1155 and 1156 plus AM5 and AM4, with a 2-year warranty. It was listed around $20 on Amazon US and rated 4.7 out of 5 from about 1,000 ratings as of November 2026.
- Pro: lowest price here
- Pro: manufacturer-confirmed LGA 1151 support
- Pro: ARGB fan and narrow body
- Con: limited overclocking headroom
- Con: 2-year warranty
Buy if you keep the 8700K at stock and want to spend about $20. Skip if you overclock or render often, where the A620 costs about $10 more.
Noctua NH-U12S chromax.black
The NH-U12S chromax.black suits 8700K owners who want a quiet, all-black single tower with a six-year warranty, for example in a living room or a studio PC used for audio work. It avoids RAM overhang, which helps on crowded micro-ATX boards with tall memory modules.
The Amazon listing specifies a 158mm height, one NF-F12 120mm PWM fan with a Low-Noise Adaptor, NT-H1 paste and SecuFirm2 mounting with an offset option. Noctua says it does not overhang RAM and does not block the PCIe slot on most ATX and micro-ATX boards. The warranty is six years.
It supports Intel LGA 1851, 1700, 1200 and 115x plus AM5 and AM4. A single fan means less overclocking headroom than the dual towers. It was listed around $100 on Amazon US and rated 4.9 out of 5 from about 5,800 ratings as of November 2026, the highest average in this guide.
- Pro: 4.9 rating from a very large review base
- Pro: 6-year warranty
- Pro: full RAM clearance
- Con: over three times the A620’s price
- Con: single fan limits overclocking
Buy if quiet running and long support matter more than price. Skip if value matters most, where the A620 offers more fin area.
Noctua NH-D12L
The NH-D12L suits 8700K owners whose Coffee Lake-era case cannot take a 155mm-plus tower. At 145mm, it fits many older and compact ATX cases with margin while keeping a dual-tower design. Hardware Secrets measured the Corsair Carbide 200R at 160mm, a reminder of how tight older cases can be.
The Amazon listing describes a 145mm asymmetrical dual-tower heatsink and one NF-A12x25r 120mm PWM fan with Low-Noise Adaptors. Noctua says it gives full RAM compatibility on LGA 1700, 1200 and 115x and AM5 or AM4, and fits most 4U rackmount cases.
It supports LGA 1851, 1700, 1200 and 115x plus AM5 and AM4, with NT-H1 paste and a 6-year warranty. Its specs come from the Amazon listing because Noctua’s site blocked our requests. It was listed around $100 on Amazon US and rated 4.8 out of 5 from about 700 ratings as of November 2026.
- Pro: dual tower in a 145mm height
- Pro: full RAM compatibility, per Noctua
- Pro: 6-year warranty
- Con: premium price for an older CPU
- Con: one 120mm fan
Buy if your case tops out near 150mm. Skip if it clears 160mm or more, where the A620 costs far less.
Thermalright Frozen Notte 240 Black ARGB V2
The Frozen Notte 240 is the budget liquid pick for 8700K builds that want ARGB on pump and fans, room for tall RAM, or a case layout better suited to a radiator than a tall tower. It needs a 240mm mount at the front or top of the case, and a little patience routing the tubes and the extra pump and lighting cables.
The Amazon listing describes two TL-E12B-S 120mm PWM fans rated up to 2,000 RPM, 72.37 CFM and 27.7 dBA, a pump rated at 5,300 RPM and 5V 3-pin ARGB connections. It recommends a case width over 250mm. We could not verify radiator dimensions for the V2.
Thermalright’s page for the Frozen Notte 240 Black lists LGA 115x, 1200, 1700 and 1851 plus AM4 and AM5, and a 5-year warranty. For a 95W chip, it is not a clear cooling step over a dual tower. It was listed around $47 on Amazon US and rated 4.6 out of 5 from about 470 ratings as of November 2026.
- Pro: 5-year warranty on the Frozen Notte 240 line
- Pro: frees space for tall RAM
- Pro: ARGB pump and fans
- Con: adds a pump and tubing
- Con: not clearly stronger than the A620 at 95W
Buy if you want an AIO look or need RAM clearance. Skip if you only care about cooling per dollar.
Buying guide
An 8700K cooler should match your clock plans, fit an older case and mount on LGA 1151 without hunting for brackets. Work through power, socket, clearance and noise in that order, and the six picks usually narrow to one or two that suit your build and budget.
Sizing the best CPU coolers for i7 8700K workloads
Intel rates the 8700K at 95W with a 4.7GHz maximum turbo. At stock, a single tower like the Spectrum V3 handles it. Six cores and 12 threads under long video exports or overclocking push heat higher, which is where dual towers like the A620 or Phantom Spirit EVO add margin.
For heavy overclocking, the EVO’s faster fans or a 240mm AIO give more headroom. Results vary from chip to chip, so no cooler guarantees a given frequency. Spending over $100 rarely makes sense for this platform unless you plan to reuse the cooler.
LGA 1151 mounting
The 8700K uses LGA 1151 on 300-series boards, with the 75 x 75mm hole spacing shared by LGA 1150, 1155, 1156 and 1200. Every pick lists LGA 115x, and all also list LGA 1700, which uses 78 x 78mm, so the cooler can follow you to a newer Intel PC later on.
Use the Intel bracket from the box and tighten screws evenly in a cross pattern. Check that your board has standard mounting holes, since some prebuilt systems use proprietary layouts that need extra parts.
Case clearance
Air picks range from 145mm to 158mm. Corsair lists the 4000D Airflow at 170mm, so all fit, but older cases are tighter, as the 160mm Carbide 200R shows. Check your case’s spec page and leave a few millimeters of margin before ordering any tower cooler.
A Noctua study reported by The FPS Review in August 2026 found 56 of more than 100 measured cases deviated significantly from their listed clearance. If you are near the limit, the 145mm NH-D12L or the 152mm Spectrum V3 is the safer choice.
Noise
Rated noise runs from 27 dB(A) on the EVO listing to 27.7 dBA on the Frozen Notte fans, but those figures describe full speed. Set a gentle fan curve in the BIOS so fans stay slow during light use. A cooler with spare capacity can stay quieter under the same load.
The Noctua picks include Low-Noise Adaptors that cap fan speed further, which suits studios and living rooms. AIO pumps add a steady sound regardless of load, so consider where the PC will sit before choosing liquid.
FAQ
These answers cover common questions from 8700K owners picking a cooler. They use the same Intel specs and listing data as the product sections above, so they stay consistent with the comparison table and do not promise temperatures or overclocks we could not verify.
Does the i7-8700K come with a cooler?
No. Intel’s spec page for the i7-8700K says the boxed chip ships without a fan or heatsink. You need an aftermarket cooler with LGA 1151 support, and all six picks here include that mounting hardware, so no separate bracket or adapter is required at all.
Is a 240mm AIO worth it for the 8700K?
Mostly for looks or RAM clearance. At 95W, a $30 dual tower like the A620 PRO SE has plenty of capacity. The Frozen Notte 240 makes sense if you want ARGB on the pump or your case suits a radiator better than a tall tower, for example a case with a large top mount.
Should I spend $100 on a cooler for an 8700K?
Only if you value quiet running and a long warranty, or plan to reuse the cooler. Both Noctua picks list LGA 1700, 1851 and AM5 and carry six-year warranties. For the 8700K alone, the A620 or Phantom Spirit EVO gives more cooling per dollar spent today.
Conclusion
Buy the ID-COOLING FROZN A620 PRO SE for an i7-8700K. For about $30 it gives a 157mm dual tower with six heat pipes and two fans, ample for gaming, editing and a moderate overclock on LGA 1151. Choose the Phantom Spirit 120 EVO instead only if you plan an aggressive overclock and want faster fans.
