Dell R720XD GPU Fans Ramp Up After GPU Install: Fix Guide
The Dell R720XD GPU fans ramp up after the installation process of a video card, which is a very basic issue that has confused a lot of IT experts, mainly all those setting up a GPU server for a variety of tasks such as machine learning, AI model training, or boosting an AI image generator. In this whole guide, we’ll take you through all the reasons behind the high fan speed, practical steps to reduce the noise, and how proper GPU hosting environments, like all those featured by GPU4HOST, can provide improved solutions.
Understanding Dell R720XD & GPU Compatibility
The Dell PowerEdge R720XD is basically a cutting-edge server mainly utilized for enterprise-level tasks. While not initially engineered for heavy GPU utilization, it’s generally reused in labs or server rooms to support quick AI GPU installations such as the Nvidia A100 or some other GPU cards.
When you install any type of GPU in a system not originally designed for it, issues such as the Dell R720XD GPU fans ramping up at high speed can occur. This can result in high noise, possible wear on components, and ineffective thermal management.
Why Do Dell R720XD GPU Fans Ramp Up?
Here are some of the basic reasons:
- Firmware Detection of any New Component
The iDRAC system (Dell’s Integrated Remote Access Controller) finds the GPU as an intense heat component and automatically elevates fan speed to avoid excess heating.
- Lack of Proper Thermal Profiles
If you are installing a GPU not conventionally supported by Dell, the server BIOS (basic input/output system) and iDRAC may lack some predefined thermal policies for the chosen card.
- Missing or Non-Dell GPU Cards
Utilizing generic or non-Dell-approved GPUs (such as third-party versions of the Nvidia A100) generally triggers hostile fan behavior, since Dell firmware cannot properly assess their cooling needs.
- Absence of PCIe Air Shrouds or Blanking Panels
A sufficient airflow design is necessary in rack-mounted servers. Missing proper airflow guides can lead to ineffective cooling and thus activate high-speed fans.
How to Fix the Dell R720XD GPU Fans Ramp Up Problem

Here is a complete step-by-step method to troubleshoot the Dell R720XD GPU fans issue:
1. Update both BIOS & iDRAC
Make sure that your server is running the updated firmware:
- BIOS: Should be up-to-date to the modern supported version.
- iDRAC: Just updated to the newest iDRAC 7 firmware.
Both of these updates generally include patches that enhance GPU detection and thermal policies.
2. Manually Set Thermal Profile in iDRAC
If your available iDRAC version supports it:
- Then, log in to iDRAC with the help of the web interface.
- Go to Thermal Settings.
- Make changes in the thermal profile to minimum power or custom, and then control fan speeds by yourself.
Bonus Tip: In some scenarios, Dell locks out fan speed control to safeguard the hardware, mainly if a non-certified GPU is installed.
3. Utilize Dell-Verified GPU Cards
Utilizing Dell-verified Nvidia GPUs can help troubleshoot a lot of detection and thermal control problems. While costly, they are natively supported by the iDRAC firmware.
On the other hand, if you’re utilizing robust cards such as the Nvidia A100, make sure that they are installed in a properly ventilated GPU cluster or GPU dedicated server setting with improved thermal proficiencies.
4. Install PCIe Air Shrouds
Guarantee right airflow by installing Dell’s official PCIe air shrouds or 3D-printed options. These support direct airflow over the GPU and avoid fans from running at 100%.
Developing a GPU Server with Dell R720XD
The Dell R720XD can be a budget-friendly option for setting up a GPU server, especially for AI model development, high-quality video rendering, or as an AI image generator backend.
However, make sure to remember all these:
- Power Supply: Make sure that you have high-wattage PSUs (1100W or more) to flawlessly support the GPU load.
- Risers & Adapters: Utilize PCIe power adapters and risers if your GPU needs more power.
- Cooling: Install additional fans or personalize cooling if the server is in a warm area.
If you are opting to scale, consider migrating to a reliable GPU hosting service provider like GPU4HOST, which provides GPU servers pre-configured for AI-based tasks.
When to Upgrade to a GPU Hosting Platform
At the time of setting up a GPU server, the Dell R720XD is the best DIY solution. You may also hit a lot of limitations when scaling AI tasks, mainly with cutting-edge GPUs such as the Nvidia A100. This type of situation is what lets GPU4HOST step in.
