N-TESLA-A100-40G-SR or TN-CMP170HX? Choosing Between Two Compatible Routes

The useful comparison is not a brand-versus-brand argument

Both products are relevant for builds around the A100 40GB, CMP 170HX, or A30 24G PCB family. The older Bykski N-TESLA-A100-X-V2 route is now represented by N-TESLA-A100-40G-SR. The Astralcooler route is the silver TN-CMP170HX.

The right question is: which block fits the card in hand and the build that will surround it? A close product title is not enough. Read the current product page, compare the gallery to the board, and confirm the installation hardware before applying thermal material.

Where the two routes differ in practice

The Bykski page presents an all-metal, LED-free N-TESLA-A100-40G-SR route with a backplate option. The Astralcooler page presents the silver TN-CMP170HX metal option and describes coverage for the GPU core, memory, power MOSFETs, inductors, and tantalum capacitors.

The finish can matter for the appearance of an open test bench or workstation, while the backplate and terminal arrangement can matter more once the card is installed in a case. Neither color nor product title is a substitute for checking the actual contact pattern.

A practical selection order

1. Start with the board

Confirm A100 40GB, CMP 170HX, or A30 24G, then compare the board photo and mounting points with the product gallery.

2. Choose the physical route

Look at block height, backplate clearance, port direction, neighboring slots, and how the card will be supported after the original cooler is removed.

3. Check the delivered parts

Review whether the selected route includes the backplate, thermal pads, plugs, screws, or other installation items shown on the current listing. Product bundles can change with revisions.

4. Build the loop after the block is chosen

Select the pump, radiator, tubing, fittings, fill point, and drain point around the installed block, not around a generic server-GPU diagram.

The honest bottom line

Because both routes are intended for the same compatibility family, this is a fit-and-installation decision more than a model-name decision. For a silver finish, use TN-CMP170HX as the product reference. For the updated Bykski route, use N-TESLA-A100-40G-SR as the current model name. In either case, verify the physical card before purchase.

Frequently Asked Questions / FAQ

Which Bykski model replaces the older X-V2 route?

The current model reference is N-TESLA-A100-40G-SR. Use the current product page and images when checking the board and mounting details.

Are both blocks intended for the same compatibility family?

The current store route positions both blocks for A100 40GB, CMP 170HX, and A30 24G. The actual PCB and supplied hardware still need to be verified before installation.

What should be compared between the two routes?

Compare finish, backplate and mounting details, port position, included parts, and service access. Product names alone do not establish a performance ranking.
