Experiments with Thermalright HR-03 rev.A

post #1 of 3
Thread Starter 
Hi,
have you ever heared about mounting Thermalright HR-03 with fan inside it? It should have quite a lot of space between that little desk that is in contact with chip and heatsink. At the same time it is awfuly large when equiped with fan from the top side. So what will happen if I will try to place fan inside. I'm not expecting super-results, just want more space and at the same time more performance than in passive mode.

Another idea: as this cooler can be mounted in top facing direction so that the heatsing is above card and directly below CPU cooler - would it be good idea to try to use fan on CPU cooler to suck air from GPU cooler in passive mode? I would use some tower CPU cooler with intake fan facing down and second fan sending ait to the top. How much do you think will it improve passive performance of Thermalright HR-03? Will it cause problems to cpu - because of preheated air on intake?

Thanks for yout thoughts
Tom

You need to make sure you have plenty of room for the fan to intake air other wise it will make excessive noise or wont get proper flow. The second idea sounds like it would be detrimental to the temperatures of the CPU. Because it would be sucking in warm air from the GPU to try and cool the CPU. Not saying it wont work, just that it isnt optimal.

Welcome to OCN, hope you enjoy our rabbit hole of knowledge. Can you fill us in on what system you are using?? By going to My profile at the top and entering in your system specs?? It would help us figure out what would be best for you

Thanks for your advice. I don't have proper PC yet, right now I'm working on my HP dv6319ea notebook. But my graphic card stopped working properly - I'm only able to run without graphical drivers installed (no 3D) and therefore I'm looking forward to make my own, silent gaming PC. I'll fill my details section with config I'm currently looking for.

About my questions. Noise from not enough space between fan - didn't know about that. I would like to mount low profile fan like Noctua NF-A9x14 PWM with only 14mm height, operating at low speeds. I guess I must try it myself to see. I was trying to google if anybody tried to mount fan inside HR-03 but not a single picture.

About second idea. here is image of what I found on the internet.


I dont want to overclock yet (i5 3570K) and if I will do so in the future I will buy own fan for GK as well. So I'm talking about not overclocked system with only basical airflow provided by front and rear 120 fans.

I have one more question about this cooler. If I install it facing up and with own fan and cpu fan will be cooled by fans that are not facing down - is it better or worse in terms of airflow than graphoc card cooler mounted facing down? I always did have feeling that card itself must be blocking hot air from going up and that diagonal airflow from botom from case fan to rear top fan will be tending to go aroun graphic cooler and not through.
