Building a home server or a workstation can get expensive very fast. You spend all your money on a high-end processor and motherboard, only to realize the stock cooler sounds like a jet engine or just does not fit in your slim rack case. Finding a reliable cooling solution that actually fits in a 2U rack mount chassis without costing a fortune is a headache.
That is where the COOLSERVER R63 4 Heatpipe 2U Server CPU Cooler Workstation Computer Cooling Fan for Intel LGA2011 1700 115X AMD AM4 comes in. I picked one up on AliExpress to see if it could handle a mid-range workstation build without breaking the bank. This COOLSERVER R63 4 Heatpipe 2U Server CPU Cooler Workstation Computer Cooling Fan for Intel LGA2011 1700 115X AMD AM4 review covers how it holds up after a month of steady use.
What is the COOLSERVER R63?
This is a specialized cooler designed specifically for 2U server cases. If you are not familiar with server gear, a 2U case is very thin, meaning a standard desktop CPU cooler will never fit inside. This unit uses four heat pipes to pull heat away from your processor and moves it toward a small, high-speed fan.
The main appeal here is the price and the wide compatibility. You can find this unit with free shipping on many AliExpress stores, which saves a lot of money compared to big-name server cooling brands. It covers a huge range of sockets, making it useful for both older Xeon builds and newer Intel or AMD desktop setups.
Real world features and performance
The build quality is surprisingly solid for the price. The base is flat and makes good contact with the processor, which is the most important part of any cooler. Because it uses copper heat pipes, it does a decent job of keeping temperatures stable during heavy tasks like video rendering or hosting a home media server.
The fan is definitely built for performance rather than silence. Since it has to move a lot of air through a tight space, it spins at higher RPMs and creates a noticeable hum. This is normal for server hardware, but if your PC sits right on your desk, you might find the noise level a bit annoying compared to a large tower cooler.
Honest pros and cons
- Pros
- The thin profile fits perfectly in 2U server racks.
- Universal mounting hardware for Intel and AMD is included.
- The price is very budget-friendly for a heat pipe cooler.
- Free shipping options make the total cost even lower.
- It keeps temperatures much lower than standard stock fans.
- Cons
- Shipping from China can take three to four weeks to arrive.
- The fan is quite loud under a heavy load.
- Instructions are basically non-existent, so you need some experience.
- There is no local warranty if something breaks after a few months.
- Customer support is limited compared to buying from a local shop.
Who should buy this cooler?
This cooler is perfect for someone building a home lab or a DIY server. If you have an old workstation board that you are trying to squeeze into a slim case, this is a lifesaver. It is also a good choice if you are on a tight budget and do not mind waiting a few weeks for the package to arrive.
You should skip this if you are building a quiet office PC or a gaming rig that sits on your desk. The fan noise will drive you crazy in a quiet room. Also, if you are new to building computers, the lack of clear instructions might frustrate you during the installation process.
What other users are saying
I talked to a few others online who bought this for their home server setups. One person mentioned it was a great way to recycle an old LGA2011 chip for a budget file server. Another user noted that while the fan is loud, it keeps their CPU cool enough to prevent throttling during long data backups. Most people seem to agree that it is a "get what you pay for" item that does the job well enough for the price.
Final verdict
The COOLSERVER R63 is a functional piece of hardware that solves a very specific problem. It is not going to win any awards for silence or premium aesthetics. However, it is an affordable way to keep a server cool in a compact space.
If you know what you are doing and just need a reliable cooler that fits your rack, it is a solid purchase. Just make sure you are okay with the fan noise and the long wait time for shipping. For the price, it is a smart pick for a budget build.
