# Fans in a Voltair

### Scope

This document covers potential fan replacements in a Voltair.

### The Issue

Occasionally an error message may display on a Voltair indicating a heating issue.

Generally, this points to a CPU fan issue. To be certain we ask that you [obtain the 30-day logs](/v1/docs/obtaining-30-day-logs-from-your-voltair) and send them to [Customer Support](https://www.telosalliance.com/support-request) for analysis.

### Replacement Fans

There are three fans inside the Voltair to help keep the unit running at an optimal operating temperature. We highly suggest [requesting a Return Authorization](https://www.telosalliance.com/Request-Product-RA) to determine exactly which fan might be causing any issue or noise. However, we do stock the three fans for field replacement.

Below is an illustration of the three fans, color-coordinated with the proper part number:

**CPU Fan** - 1239-00038-100

The CPU Fan is held to the motherboard with Phillips screws.

> [!WARNING]
> If a newer fan is replacing an older, original fan, then four screws (1301-00198) also need to be ordered as the newer fans are thicker than the original.

**Side Chassis Fan** - 1239-00028-100

![](https://cdn.document360.io/57e3cd80-d493-453c-9672-ad1b043dadc3/Images/Documentation/d7e8333e-743b-4687-bb5f-176f58c090f9-image.png?sv=2026-02-06&spr=https&st=2026-11-12T11%3A53%3A02Z&se=2026-11-12T12%3A53%3A02Z&sr=c&sp=r&sig=DfaYFMOCHdovDIivpxSCQvftghzL3HY54b9euQ3Uq2o%3D)

The Side Fan is held to the chassis by nylon locknuts. The mainboard will need to be removed and a thin-walled socket wrench will have to be used to remove the nuts and fan.

**Rear Case Fan** - 1771-00110-100

![](https://cdn.document360.io/57e3cd80-d493-453c-9672-ad1b043dadc3/Images/Documentation/25731b3d-f5a8-4816-9014-24f250a1697b-image.png?sv=2026-02-06&spr=https&st=2026-11-12T11%3A53%3A02Z&se=2026-11-12T12%3A53%3A02Z&sr=c&sp=r&sig=DfaYFMOCHdovDIivpxSCQvftghzL3HY54b9euQ3Uq2o%3D)

Like the Side Fan, the Rear Fan is also secured to the chassis using locknuts. While the mainboard may not have to be removed to replace this fan, a smaller socket wrench will have to be used as there is a lot of space to remove the fan.
