Zalman CNPS10X Performa Black Top PCIe Slot & VRM Clearance
The Zalman CNPS10X Performa Black offers a sleek matte-black single-tower cooling solution targeted at budget and mid-range PC builds. Featuring an oversized 135mm turbine blade fan attached to an aluminum fin array with asymmetric heatpipe shaping, it delivers low acoustic output alongside reliable thermal performance. However, because its 135mm fan frame extends slightly wider than traditional 120mm cooler towers, verifying top PCIe expansion slot clearance and motherboard VRM clearance is necessary before building.
Specifications and Spatial Metrics
The table below outlines the core measurements defining fitment for the Zalman CNPS10X Performa Black.
| Parameter / Component | Dimension Spec | Fitment & Clearance Consequence |
|---|---|---|
| CNPS10X Performa Overall Height | 155.0 mm | Fits budget and mid-tier ATX mid-tower chassis |
| Fan Frame Outer Dimensions | 135.0 mm x 135.0 mm | Extends 5.0 mm wider than standard 120mm towers |
| Gap to Primary PCIe Slot (Slot 1 Position) | 8.0 mm | Clearance gap to GPU metal backplate |
| Heatpipe Count & Base Construction | 4x 6mm Direct Touch Copper | Asymmetric offset angled away from memory slots |
135mm Fan Frame Width and PCIe Slot 1 Clearance
Standard single-tower CPU coolers utilize 120mm fan frames measuring 120mm in total width. The CNPS10X Performa Black equips a custom 135mm turbine fan designed to maximize airflow while reducing motor hub noise. This extra 15mm of fan width means the housing extends approximately 5mm further toward the primary expansion slot than typical 120mm coolers.
When installed on an ASRock B650 Pro RS AM5 ATX motherboard—which positions its primary PCIe 4.0 x16 slot in Slot 1—the lower plastic housing of the 135mm fan leaves an 8mm gap to the backplate of the installed graphics card.
Even when paired with thick metal backplates found on modern GPUs like NVIDIA RTX 4070 Super graphics cards, the 8mm clearance gap prevents physical contact, ensuring safe electrical isolation and smooth card insertion.
Chassis Headroom and Memory Compatibility
Standing exactly 155mm tall, the CNPS10X Performa Black fits comfortably into almost all standard ATX mid-tower enclosures without hitting the side glass window. Key layout considerations include:
- RAM Clearance: The asymmetrical heatpipe bend shifts the fin tower backward, providing 100% RAM slot clearance for memory modules up to 40mm tall under the front fan shroud.
- VRM Heatsink Clearance: Clears rear VRM heatspreaders up to 38mm in height without fan housing friction.
- Power Supply Pairing: Highly efficient cooling for 65W to 120W CPUs makes it an ideal pairing with budget-friendly 650W 80 PLUS Bronze power supplies in mainstream gaming systems.
