When you look at a 3-pin plug, it has two ridges on the top. If you compare a PWM plug, it has those same two ridges, but a lobe off to the side contains that 4th wire. A 34-pin plug can fit into a 4-pin socket, but a 4-pin plug cannot fit into a 4-pin socket. Fans 101. Ask Tator Tot.

In this case, the review cited by OP shows a 4-pin plug on what presumably are 4-prongs (what you would find inside a PWM socket). That suggests a PWM fan. The Magma is a 3-pin fan. (I had one; also, Enermax still sells it and it seems to be a 3-pin)(look at this photo: https://www.newegg.com/Product/Produ...82E16835214001).

If OP's fan is PWM, and can get one, I can suggest the Cluster Advance.

Edit: I still recommend your suggesting a trial re-lube; that costs almost nothing.

I have to admit I am not quite grasping the 'a 4-pin plug cannot fit into a 4-pin socket'

I think neither is good both are old designs AFAIK and I am pretty sure there must be a better option for the money tell us about any stores in rumania and we'll search for a PSU for you

I did not proofread well enough. What I meant to say is -- by design -- a 3-pin plug will fit in a 4-pin socket. Think voltage-controlled fan in a PWM socket. But a 4-pin plug will not fit in a 3-pin socket. A 4-pin plug will fit in a 4-pin socket and a 3-pin plug will fit in a 3-pin socket.

Like this is a 3-pin fan:
This is an Enermax Magma.

Here is a WPM fan, the Enermax Cluster:
Note the similarity between the plugs.

Many is the time I have inserted a 3-pin plug (Gnd-12v-RPM) into a 4-pin socket (Gnd-12v-RPM-PWM). Only if you break a sidewall will a PWM plug fit a voltage-controlled socket. Of course, most fan-testers have done exactly that at some point.

not on (older) Enermax...
You can't replace the fan there easily, they did something totally proprietary...
