Does WHIM solve the dark matter problem?

In summary, recent progress has been made in the direct observation of the warm-hot intergalactic medium, also known as the "whim." However, it is not enough to account for the quantity of dark matter in the universe, which is necessary to hold galaxy clusters together. This can be seen through x-rays in galaxy clusters, where the whim only makes up a small fraction of what is needed. The bullet cluster is a prime example that directly rules out this theory.

TL;DR Summary
Does the Observation of whim can solved the problem of dark matter
Direct Observation of Whim (The warm–hot intergalactic medium) has known a lot progress recently. Does whim could be enough to amount to the quantity of dark matters in the universe, therefore solving the dark matter problem? If not, why?

Short answer: no, for many reasons. First, there isn't enough of it. We can see this matter quite clearly in galaxy clusters through x-rays, and it only amounts to a small fraction of what is required to hold the galaxy clusters together.

There's lots of other reasons why this can't work, but that's the start of it. I recommend looking up the bullet cluster for a pretty direct observational example that rules this out directly.
