I wanted to put this out there on the overclock.net, corsair, and ROG forums to see what the users, moderators, and (maybe if I’m lucky to get a response from Yellowbeard or Ramguy) the manufacturer have to say.
Here’s my specs:
Intel Core i5 3570k
ASUS Maximus Gene V
eVGA 660 Signature2 OC edition
2x8gb G.Skill Ares 1600 RAMApevia QPack2 case
Ambient temps are around 21 degrees Celcius
I’m currently using the stock Intel fan and get temps of about 88 degrees Celsius when running Prime95. I have the processor overclocked to 4.2ghz with -0.01 offset voltage, which raises the temperature to about 91. Obviously that’s way too high. For now, however, I’m ok to keep it overclocked at 4.2 as the processor doesn’t usually go above 65 degrees when gaming. I would like to get it to 4.5ghz, but want to get a better cooler first.Your Apevia case will always be a challenge with higher OC's and cooling, not to mention that stock 500w PSU will be the main suspect should BSOD's start to occur with even mid-range OC's especially in an overheated case! Sooo if a case/PSU upgrade isn't in the near future for more serious overclocking and your using this rig mainly for gaming you'd be fine with either the H55 or H60. Especially since you won't notice much of a difference in gaming with a 4.2 vs 4.5 OC! The 2nd gen H60 is a better unit, many are puzzled why Corsair didn't differentiat it from the original with a H60i or H65 designation. Something was wrong with Dustin's tests [HERE] that day as even the H100i tests were all out of whack and not consistent with his previous stellar reviews like [HERE]I'd go with the "HardOCP" review comparing the 2.
NOW if other upgrades are in your near future and you want to eliminate cooling as a restriction to higher overclocks, I'd go with the H80i (externally mounted in the back?) or I think it would look cool to mod an H100i into the right side panel in an exhaust config which would also help with the extremely poor case air circulation (note: reverse the rear 120mm from exhaust-->intake). The H100i will outperform the H80i "exponentially" as the demand/stress gets higher. What's the worst that could happen? You get frustrated with the Apevia/500w PSU and upgrade with more serious overclocking in mind and your ready to go with the H100i ... ALTHOUGH since your not so concerned with $$$ ... I'd take a serious look at the Swiftech 220 that "pc-illiterate" linked for only $20 more ... the "Quality" and "expansion" potential is unmatched IMHO! More "Color" comments below
I would like to get a CLC as my case can only fit a CPU fan up to 76 mm in height. I’ll need to mod the case to fit the rad, which will be mounted on the outside of the case. I can’t imagine that I’ll be able to do anything other than an exhaust setup. There is a similar build below:
You can kind of see in picture 16 the holes that will need to be cut. I also plan to cut out the plate covering the fan for extra airflow. I have an 80 mm fan in the front of the chassis pulling air into the case.
I’d prefer NOT to use corsair link for two reasons: 1.) I’d like to keep the number of cables in my case to a minimum, and 2.) it doesn’t seem that stable yet.
But which fan to buy? Here are a couple examples of the conflicting information:
Anandtech shows the H55 beating the H60 by about 3 degrees. They attribute this to a better waterblock:Something is amiss with Dustin's review (see above), I also don't believe the H55 block is superior to the 2nd gen (2013) H60, that's a question for Corsair George?
“Unfortunately, part of the reason the H55 looks so good is because the H60 performs so poorly. The H60 runs $10 more than the H55 for an arguably better PWM-controlled fan and a somewhat lesser quality waterblock. In this corner of the market, there's really no legitimate reason to spend up on the H60 when the H55 performs as well or better for less.”
Hard OCP shows the H60 beating the H55 by about 2-4 degrees when overclocked. They also attribute this to a better waterblock:
“It is able to best the original by about two degrees which is impressive considering it uses the same radiator and pump, so surely this points to a more efficient coldplate design.”I believe this makes more sense and is more Accurate!
Hard to decide which one! For the sake of argument, let’s ignore cost. They are all pretty close to each other in price and $50 one way or another is not going to persuade me. I do care about noise level. I have come up with some questions that will help me decide:
1. Does the H55 or H60 have the better waterblock? Agree w/HardOCP
2. With a mild overclock (4.2-4.5), is a H55 or H60 enough to keep the temps below 50 degrees over ambient when running Prime95? Maybe@4.2 / I doubt it @ 4.5GHz
3. From the pics and reviews, the waterblock on the H60 seems much easier to install. Is that correct? They are all pretty simple
4. Are the H50 and H55 consistently ranked higher than any of the other coolers just because they are cheaper? Define 'Ranking" /$$$ yes /performance NO WAY!
5. Is a 27mm radiator too thin to benefit from a push/pull configuration? Usually / depends on setup/case/fans/ambients/how high of an OC?
6. If a 27mm radiator does benefit from the push/pull, would it be enough to keep the temps below 50 degrees over ambient? NO
7. Can you run a H80i without CorsairLink? YES
8. Would a H90 with a 140>120mm adapter work (essentially acting as a shroud)? Yes
9. Do the preliminary tests for the H90 show it works better than the H80i? Yes IMO 3-5c cooler and Quieter! BUT if it costs as much as the Swiftech220 ($140) I'd mod/GO w/that!
Side-issue – I have a 3-pin 120 mm case fan. I’ve noticed my RPM’s are not consistent. Does that mean my motherboard is modulating the voltage?How inconsistant? 50-100rpm? is OK
If so, is there really any advantage to PWM fans? PWM fans are just more versatile for control / Depends on your mobo's bios features and how many fans you want to control / that's a pretty versatile mobo with good fan control features
Based on Anandtech’s radiator fan review and the fact that they match my system, I’ll most likely swap out any stock fans for the Enermax Magma fans – the ones on FrozenCPU are red and black.
http://www.anandtech.com/show/6391/120mm-radiator-fan-roundup-part-2-fan-harder/7Seriously consider upgrading your case/PSU, I think you'll be much happier in the long run as your Overclocking skills expand, we didn't even discuss GPU OC's heat/stress which will show greater benefits in gaming than a cpu OC will
I really appreciate the information these forums contain. Hopefully this post will help others asking the same questions.
