Sorry to say that you are wrong here. Every fan has a center, that center is the dead spot. Only if you place the fan about min. 1 inch from the rad, the dead spot will disapear, due to the movement of the air.
Also, if the fan is direcly on the rad, the pressure it needs to press the air through a small surface (only the fan area) is much higer then when it is 1 inch away from the rad. The area it can cover then is much bigger, and therefore it needs less pressure.
To RedPhoenix: a 50c drop in a minute? That’s great!
I guess the water was standing still in the rad at that time. When the water starts flowing, this will only get a lot better.
Looks like you got "nothing to worry" about.
Just a few ideas:
- Blowing the hot air inside your case will be best for the watercooling, as it is beeing cooled with "cold" fresh air, but you need to be sure that the hot air can leave your case! So make sure you have an equal or more fans getting the hot air out.
- A to high overall system temp will make other items fail (memory, chips on your main board etc.)
Using the "hot" air from your case (so not sucking but blowing) will decrease your cooling performance, but you will gain on system performance/stability.
It's a bit trial and error. First let the fans suck the fresh air in, and measure the temps in your case If they are not to high, it's all OK.
If you get high temps inside your case, and your system is getting unstable, turn your fans around, so you reverse the airflow (but leave the PSU for what it is) your cpu temp might go up a bit, but you will run a rock solid stabile system.
What are you planning to cool? CPU, GPU?, North bridge? use peltiers?
