Case fan for compact builds promising effective cooling in tight spaces, ARCTIC P8 Slim PWM PST Fan. Quiet operation at low speeds keeps living rooms and media centres peaceful. Will the narrow 15 mm profile and PWM sharing suit an HTPC or single-board computer build?
⚡ At a Glance
- • Static Pressure: 2.35 mmH₂O static pressure with 22.5 cfm (38.23 m³/h) airflow, optimised for restricted air channels
- • Best for: Small form-factor PCs, HTPCs and single-board computer projects needing low-profile cooling
- • Not ideal for: Setups where a full-height 25 mm fan already fits and higher unrestricted airflow is required
PWM-controlled fan runs between 300 and 3000 rpm and includes a PST connection for synchronised operation. Low installation height and efficient operation suit small, energy-conscious systems.
Fits Narrow Cases – Thanks to 15 mm installation height
A slim 15 mm frame reduces the physical depth compared with standard 25 mm fans, allowing mounting in tighter gaps. Mounting holes and dimensions match typical 80 mm fan placements while keeping clearance minimal.
Enables effective cooling in ultra-slim HTPCs and SFF desktops without altering case layout or removing internal components.
Synchronised Multi-Fan Control – With PST daisy-chain socket
An additional socket next to the plug connection permits fans to be connected in series so the PWM signal is shared across linked units. The PST chain keeps fan speeds unified from a single motherboard header.
Keeps multiple fans running at the same speed from one PWM source, reducing cable clutter and simplifying fan management in compact builds.
Variable Noise and Speed Control – Thanks to 4-pin PWM and wide rpm range
Four-pin PWM control adjusts fan speed across a 300–3000 rpm range, allowing precise regulation of cooling performance. Lower rpm settings reduce acoustic output while higher rpm settings deliver increased airflow and pressure.
Delivers quiet idling during light tasks and the ability to ramp up cooling under load, matching acoustic needs to performance requirements.
✨ The 4 Key Reasons for ARCTIC P8 Slim PWM PST Fan
- 15 mm installation height — Fits ultra-slim cases and constrained mounting points reliably.
- PST daisy-chain socket — Synchronises multiple fans from one PWM header for tidy cable management.
- 300–3000 rpm range — Allows near-silent idling and rapid ramp-up for intense cooling demands.
- Low current draw (0.095 A) — Minimises power use and eases load on motherboard fan headers.

❓ Frequently Asked Questions
Q: Can the fan fit in ultra-slim cases?
A: Yes, the 15 mm installation height makes it suitable for small form-factor cases and installations where a 25 mm fan does not fit.
Q: Can multiple fans be connected and synchronised?
A: Yes, the PST daisy-chain socket lets additional fans be connected in series so PWM signals control multiple fans together.
Q: How is noise and speed controlled?
A: Four-pin PWM enables speed control from 300 to 3000 rpm, reducing noise at low speeds while allowing higher cooling performance when needed; user feedback notes quiet operation at low RPMs.
🏆 Our Verdict
The ARCTIC P8 Slim PWM PST Fan suits builders of HTPCs, mini-ITX systems and single-board computer projects who need low-profile cooling. A 15 mm frame combined with PWM control, a wide rpm range and PST daisy-chaining makes the fan highly adaptable for compact builds. Low power draw and practical features deliver strong long-term value for small-system enthusiasts.
