Industry Challenges

Understanding the specific thermal and environmental demands of PC System Integrator Cooling environments is the foundation of every Herays solution.

PC system integrators — building branded desktop systems, industrial PCs, embedded computing platforms, and ruggedized workstations for resale — need cooling fans that combine reliable thermal performance with predictable long-term supply availability, consistent quality across production batches, and documentation that supports CE and other regional approvals for systems sold globally. The individual fan cost matters less than total system cost of ownership: a fan that fails in warranty is far more expensive than a slightly more expensive fan that doesn’t.

  • Consistent inter-batch quality — OEM system builders cannot tolerate acoustic or performance variation between production batches. Fan suppliers must provide batch-traceable test data and control bearing specification, blade tooling revision, and motor winding specification within acceptable tolerances across deliveries.
  • 12V DC with 3-wire or 4-wire connectors for motherboard integration — standard ATX fan headers supply 12V and expect a tachometer signal on pin 3. PWM control (4-wire) is required for systems with active thermal management firmware.
  • CE and RoHS documentation for EU market access — system integrators selling into the EU must include CE-marked components. Fan supplier must provide Declaration of Conformity, test reports, and RoHS material declarations at the component level to support system-level CE marking.
  • Long supply chain stability — PC system integrators build systems with 3–5 year production runs. Fan components must remain available — or have qualified alternates — throughout the product lifecycle without requiring thermal re-validation of the complete system.
  • Application-specific airflow requirements — from slim form-factor mini-PCs requiring 60–80 mm fans at low airflow to tower workstations needing 120–140 mm fans at high CFM, the integrator’s component library must cover the full range without sourcing from multiple unqualified suppliers.

Herays supplies PC system integrators with 12V DC axial fans across standard form factors, with CE/RoHS documentation, consistent batch specifications, and OEM volume pricing. All HR1225 and HR1238 variants are available in standard ATX 3-pin (tachometer) and 4-pin (PWM) connector configurations.

  • HR1225 12V — 120×120×25 mm, 134 CFM, ball bearing, CE/RoHS. The standard desktop tower and ATX chassis fan size; covers the majority of mid-tower and full-tower system integrator applications.
  • HR1238 12V (−SF) — 120×120×38 mm, 186 CFM, with tachometer output. For high-performance workstation builds, server-grade desktop platforms, and systems with high-restriction heatsinks where standard 25 mm fans are marginal.

Herays also supplies compact 60 mm, 70 mm, and 80 mm fans for mini-ITX, NUC-style, and embedded PC platforms. Contact us with your chassis dimensions and thermal budget for the appropriate specification.

What documentation does Herays provide to support CE marking of my system? Herays provides a Declaration of Conformity, CE test report references, RoHS material declaration, and component datasheet for each fan model. These documents satisfy the component-level requirements for inclusion in a system-level technical file for CE marking under the EMC Directive and Low Voltage Directive.

Can Herays supply fans with custom labels or OEM branding? Yes. OEM label printing on fan frames, custom connector pinouts, non-standard cable lengths, and branded packaging are all available for qualified volume orders. Contact Herays with your branding requirements and estimated annual volume.

How do I qualify a replacement fan when the original goes end-of-life mid-production run? Herays maintains consistent mechanical dimensions and electrical specifications across production generations of the HR1225 and HR1238 series. When a model revision occurs, we provide advance notice and supply both the current and replacement specification side-by-side for thermal re-validation. Herays can also hold safety stock for customers with long production commitments.
