H70 cooling ducting?

post #1 of 10
Thread Starter 
Hi all,

I am new on this forum, I used to do overclocking back in the day but now I have a nice AMD 965 BE to play with so I am going to upgrade the cooling etc very soon. I am planning to get a H70 at some point although I was looking at getting a Noctua NH-D14 air cooler but I decided that I wanted to go for something a bit smaller as I don't have a full sized tower case etc.

Although I am going to get a H70 I need some opinions/help on cooling the radiator etc.

As the air cooling for the H70 rad uses the exhaust as an intake I will have cold air being pulled in, but then heated, then blasted into the case, not good. I will of couse have side fans to get rid of this but I thought I would ask about ducting.

The front of my case is meshed for good air flow, I only have a DVD drive in the large bays so there is plenty of room for something else near the top of the case.

I was thinking of perhaps running a duct from the H70 to the front of the case, kinda like making a wind tunnel, so it will be intake, fan, radiator, fan, ducting to the front.

This would mean that the hot air is channeled through the case but without actually being pumped directly into it, meaning I can use the other front and side fans to cool down the case with the mobo and gfx card etc without having to worry about the random air flow from the H70 messing up the flow.

What does everyone think of this idea?

Thanks in advance

Alot of people just flip the fan an make it an exhaust fan.

If you do have good airflow through your case it will not make too much of an increase of temps.

you can do that or you can add extra fans

Yeah, I think I will probably make the fans an exhaust push pull setup, perhaps I could put in a bend to one side so it pulls air in from the side of the case, so it could just got side, duct, fan, rad, fan exhaust?

Are there any examples of people ducting the H70/H50 in the case? I guess the radiator is just like a tower of cooling fins within the case. My case unfortunatly has the PSU at the top, but I guess that might help with drawing the hot air from the top of the case out the back.

Dont over-think it, m1tch. In all honesty, the H70 with both of its fans and the thick radiator does take up just as much room as the NH-D14 inside your case.

Here is what it looks like when I used to have one.



..makes my 700D look like a mid-tower case LOL

Ah ok, hmm well at least you can get to the RAM slots with the H70 vs the NH-D14!



Did you find there was much heatsoak within the case at all?

Yeah, the thing is the NH-D14 cools better than the H70, which is very impressive for an air cooler, plus its a bit cheaper, but at the cost of heatsoak and space.

I kinda figured that spending a bit more on getting a H70 and then perhaps changing the fans or running them at max is better than spending a bit less, getting a maxxed out air cooler and then have to spend more on cooling the case.

With the H70, sure the radiator and fans are quite big and its a bit more, but check out the better air flow over the Mobo, RAM and GFX card.

@itcrashed (great name btw) did you run yours at full tilt on OEM fans or did you restrict them to 1600?

I tried several things...
OEM restricted and full bore...both speeds created way too much noise for my liking. When I removed either the push or the pull fan, the noise was more acceptable.

I also replaced the fans with Scythe S-Flex fans in the hopes of being able to reduce the noise with push/pull. Same result. Using two fans was too noisy and using one fan was perfect.

I switched back to the H50 and was happy for about two weeks until I decided to do a full custom loop

Exactly. The noise is almost enough to drive you crazy with 2 fans going all out. My friend has one of these inside his case and it's so annoying lol. He says it performs really well and he has it setup to exhaust. From what I'v read, having it set to exhaust is better in most situations. Although it is taking warm air from inside the case, the temps on the cpu only changed like 2C on my friends rig. Apparently when he had it on intake, although the cpu was a few Celsius lower, his case temps rose quite a bit. Not a big deal if you have good airflow in your case though. Now this is just what I was told, no experience with it personally except for listening to those damn fans lol.
