CPU overheating with Corsair H50?

So, I have an i7-4790k at stock 4.0Ghz. I'm using the H50 with a push-pull config. My idle is about 38c, which I'm guessing is bad. Now, the problem is that when I play a simple game like CS:GO, it reaches 70c! I did not install the cooler, so should I reinstall it to see if there was just not proper contact or too much/too little thermal paste? Thanks :)

If you didn't install it personally, yeah, I'd definitely check the whole installation. First, make sure the pump is plugged in to the proper header and working. If it is on a motherboard fan header that can be controlled from Windows, check that it has an RPM reading. Then, make sure that the block is flush, even and properly bolted in. Those blocks come with a pre-applied layer of paste on them. You should wipe that off anyway and put something better on it. Then, make sure the fans are blowing the right way.

38c at idle and 70c under load isn't too bad depending on what voltage the pump and fans are running at as well as the air flow in your case. I'm using an H60 (also push-pull) on a similar CPU (E3-1230v2) and the pump and fans are at the lowest possible speeds and on 5 volts to keep noise to a minimum. It is also in a tiny Prodigy case with terrible air flow. It is getting similar temps. Your room temp is also a factor. My room is usually in the 70-75F range. If I upped the pump and fan speeds, the temps go down a few degrees. My Hyper 212 Evo actually performs better.

Ok, I defiantly will do. First off, as I do not have any spare thermal paste lying around, I will most likely (depending on how much was applied), will be reusing it, meaning leaving it on just to check if there is excess paste. The pump is plugged into a CPU_Opt 3pin connector running at 1366rpm. All of my other fans, including the fan on the front of the raidiator, are running between 1100-1200rpm. So it is most defiantly working. Secondly, the first fan I have/had on the radiator is a basic Coolermaster fan with the thick blades. That is on the back, and my new AF 120 is on the front. So should I remove the CM fam, and replace it with the AF 120? This will be pulling air through the raidiator and reducing it to just a pull instead of push-pull. The instructions show it blowing air into the case, which is a bit confusing. Anyways, if it is simply just a matter of incorrect installation, then I will be reusing the paste by taking off excess if there is any, and reinstalling it. If there is too little, then I will probably order something like MX4.
Again, thanks :)

2 fans in push-pull are better than one pull so just leave it in that configuration with both fans blowing out of the case. I'd put the AF120 in as the push fan and the stock one as the puller since that is what it was designed for. You should just order the MX4 regardless and apply it. It might help bring temps down a few degrees but don't expect anything dramatic. You could order a couple of high static pressure fans that are designed for radiators but on the H50 I doubt that you'll see any significant gains over what you are using right now. They might quiet the system down at the same RPM and lower the temps a few C but that'll be about it. You'll need a better cooler to get significantly better idle and load temps.

Also, I edited my first reply. Those temps don't sound too bad for what your are trying to cool, a stock clocked i7. You'll get similar temps with a $20 tower cooler like the Hyper 212. The H50 is entry level and will give you entry level performance. Case air flow, room temp, the way your PSU's fan is situated and the type of GPU you are using are also factors in the CPU's temps. If you have a non-reference beast of a GPU that is spraying hot air all over the inside of the case, temps will be higher. I'd check the PSU as well and make sure that the fan is blowing air out of the case and that all your case fans are pointed in the optimal direction as well.
