Just wondering if anybody can absolutely verify that using the H80i will be suitable for use to cool an FX-8320 on a Sabertooth board. I can't go with the H100i or any of the 240mm radiators because my Bitfenix Comrade case doesn't look like I can even mod it to work. I've tried every possible mod configuration in my head and can't figure any way one would work. So I'm just looking for confirmation that the smaller cooler should do the job.

I realize I could use one of the air coolers like the cryorig r1, Noctua Dh-14 or 15 or the Phanteks ph-tc14pe but they are all just a little too big for the case and honestly will almost entirely block airflow from the case fans. I do plan to OC but it's doubtful I'll go past 4.3 just for the sake of longevity. Thanks.

It does appear (looking at the specs for your case and the CLC at Newegg) that the H80i can replace the 120mm rear fan and be mounted there.

Have you considered the CM Hyper 212 EVO (with 2 fans)? It would lower your costs and still perform quite well (your desired OC should be easily achievable).

The fans would blow in the same direction as the rear fan so they would help move air in the right (most effective) direction, BTW.

Yeah, I already went that route, with the EVO, and I've got a previous thread here on that failure to launch. Couldn't get it to cool, at all, went nuts trying to figure out why I was getting better temps with the stock cooler, then after about ten attempts I gave up on it and stayed with the stock cooler. Then a few day later I accidentally discovered that the center thumb screw actually does tighten down, which is never mentioned in any of the online tutorials nor it included in the included manual.

That worked great for about two days, then the frackin' fan bearing started screaming. Rechecked the fan mounting and there was no interference anywhere, it just died. Even took it off the heatsink and powered it through a bench located psu. Same noise. Contacted both the Egg and Coolermaster and was told that because I had used 1000 grit sandpaper on the bottom of the heatsink to flatten what was clearly not flat, they couldn't warrant it.
I told them I didn't want anything but the fan warranted and that they fan failing has nothing to do with the heatsink. They informed me that they could only replace it as an entire unit, not just the failed fan.

So I'm done with Coolermaster. I can't really blame the Egg for anything because they don't replace parts in any case. So I need to go a different route and since I'm planning to OC anyway and have the cash I might as well get the best rig I can fit in this case, or make fit in this case with some modifications, so that if I decide to upgrade things later I already have a cooling solution that's likely to still be relevant.

You could just replace the fans on the EVO. You don't have to use CM fans. I have a rig that I replaced the CM fans with 120mm Noctuas (PWM types). They are expensive, but AWESOME.

Yeah, I guess I could but the temps I was getting with the EVO setup, when it worked, wasn't anything spectacular. I don't really have much faith that it would be very effective if I wanted to try and get like a 4.3 OC or thereabouts. Even just going to 4 is doubtful with the temps I was getting at stock frequency.

I already cut a nice hole in the top and mounted a Noctua there as an additional exhaust fan. I'm thinking I might be able to just make another hole and then join the two holes so it's a nice oblong cutout and mount the H100i there.

I'd have to move my DVD/RW to a lower bay, which is no problem, to accommodate one of the fans, and I think it would work pretty well with two front intakes, one rear exhaust and then the radiator up top with dual fans exhausting in a push setup through the radiator.

The radiator would be mounted outside the case and the fans would be mounted inside the case but there would only be just the thickness of the case between them. That way none of the heat radiating from portions of the radiator that are not directly impacted by the fans won't be allowed to remain in the case. What do you think?

External rads can lower system temps. They can be awkward when moving/servicing your rig. Just something to keep in mind.

I'll probably build a small cage around the radiator and fasten it down like the old style case fan grills were attached. I don't plan to have to move it around much and where it will be sitting it can be easily worked on if needed. I think I might just do this unless somebody has a better suggestion/solution or a good reason why it's a bad idea.

Well, I changed directions and went with the ASUS SABERTOOTH 990FX R2.0 and the Noctua NH-U14S. After doing some further reading on liquid coolers it seems there are a lot of issues with pump noise on AIO setups and I just didn't want to deal with it. Maybe later down the road after they get ALL the bugs worked out I'll switch over but for now the reviews on noise vs performance made the Noctua seem like a good compromise.

And since it's smaller than a lot of the top air coolers but performs within a few degrees of them and has PWM along with a fairly low noise level I figured I'd try it and see. Hope I didn't make a poor choice with either purchase but I think it will work well. And, it will be much less work since I won't need to mod the case.
