Corsair H80 isn't doing me any justice!

I purchased an H80 in the early of January, and I thought it kept my temps cool, it kept my i7 960 STOCK at 40*C in idle. Then I did an overclock 4Ghz because I'm getting bottlenecks with my GPU. I get 48*C on Idle, and I've seen people get higher clocks than me with better temps? I even applied Shin Etsu thermal paste I got yesterday. Still idles about 44*C now. I wonder if there's anything wrong. I've always had H80 for about a year, (In Jan I had a leakage and it broke so I bought a new one)

This is actually the method Corsair recommends in their installation manual/video; bring in the cool air from outside the case. It's jacked up and goes against every principle of traditional front-to-back airflow. But...

44 idle is about what I get on my i7-4770k at 4.3Ghz with the h80i.

My i7-950 at 3.85Ghz got about 40C at idle with a tuniq tower 120 extreme heatsink and fan, so that seems normal.

What are your temps under load? I'm not too impressed with the h80i in that regard, I see spikes as high as 84C under huge loads, and right around 80 after an hour or two gaming. Been messing with the fan profiles a little as well, don't seem agressive enough.

Are you sure that everything is seated correctly? Try this:

1. Remove heatsink.
2. Clean heatsink and processor IHS (the metal on top) with isopropyl alcohol and a lint-free cloth/rag/etc. Make sure there's no thermal paste whatsoever left.
3. Apply dot of thermal paste (image below).
4. Reseat heatsink.

My i7-960 used to idle in the the 30Cs with an H50 at stock speeds. I used AS-5 (the old de facto). An overclock to 3.8GHz under load put my temps in the mid-high 70Cs.

Did you use the 3-line method to apply the thermal paste?

Assuming you're using a push/pull setup with your fans, are they blowing in or out? Have you tried switching the direction?

It could just be a general air flow issue? What is the make/model of case you use for this build?

I used the dot method as shown in the pic on ihogs' post. All fans are blowing in to the case. On load, I've gotten up to 70*C.

You need exhaust fans as well. We want to move air through the case, not just blow it around. You have to remove the hot air.

Oops, I meant that the fans attached to the radiator are blowing in xD. I have x2 200mm NZXT fans exhausting out on the top of the case.

With this type of processor, the 3 line method is advised (two short lines about a third of the way from the east and west edges 25% long and one long line up the middle 50% long; all very thin lines).

At any rate, the H80 isn't all that great. 70C is a pretty normal high-end temp for the i7-960. Any of the Corsair self-contained liquid system's I've used don't give phenomenal cooling. They're around as good as a high-end air cooler. Still nothing compared to what people get with a custom water loop.

I see the advantage with an H80 or H100 as moving the bulk of the CPU cooler away from the processor and to an exhaust port. This makes it easier to work in your case. I wouldn't expect too much from these things though. From an aesthetic standpoint, I also like to be able to see my RAM and other parts of the motherboard and prefer not to have the covered by a large metal block/fans.

I find reviews on the cooling ability of these coolers to be over-rated for sure. They definitely do a better job than stock solutions though.

You're blowing hot air from the rad into the case? Why?

What is the full fan config?

It's jacked up and goes against every principle of traditional front-to-back airflow. But front-to-back airflow was also the standard prior to companies making cases with top exhaust ports which support the fact that hot air will rise. Some of the the Silverstone cases are all about bottom-to-top airflow which makes a heck of a lot more sense to me.

So what would you recommend me to do?
