Antec Kuhler H2O 620 working properly?

Hello everyone:

So I just installed this on my system. I had to remove the fan on the back of the case to install it, but I installed an additional fan on the radiator.

My issue right now is that I'm running exactly the same temperature as with my previous air cooler (Cooler Master Hyper 212 plus), in which I also had installed an additional fan.

Idle, the temps are oscillating between 39C and 43C. Under stress it always gets in the mid to upper 80sC. Playing games spikes in the low 60sC and usually stays in the high 50sC. I'm in S. Fla, so temps outside get pretty high, between 85F (30C) and 95F (35) this past week. I keep my AC usually at 70F (21C). This is my system:

Thermaltake Level 10 GT Case
Intel i7 2600K Quad OCd @ 4.6 Ghz
ASUS Sabertooth P67 Motherboard LGA 1155
Antec Kuhler H2O 620 Liquid Cooler
Corsair Vengeance 16GB @ 1866 Mhz
2 X EVGA Nvidia GTX 460 SC 1024GB SLI
Corsair TX750W PSU
Crusial RealSSD C300 128GB SATA III 6Gb/s (Boot)
WD 1.5TB HDD (Files)
Hitachi 2TB HDD (Backup)
Memory Card Reader 3.5" bay.
Windows 7 Home Premium SP1

My questions are:

Do these temps sound right?

Is it normal that the air cooler would match the liquid cooler's temps?

Should I remove the stock TIM and apply Artic Silver 5?

Thank you very much for your help!

I replaced the fan that came with the cooler. Put one with more sta pressure pushing and put a one with good cfm pulling.

Hi,

I have ASUS Sabertooth P67 Motherboard LGA 1155 and I want to put a Antec Kuhler H2O 620 Liquid Cooler on this but it's not possible on the mainboard.

The adaptator (Antec) is for the socket 1155, 1156, 775, 1366 and AMD

When I want to do the installation, the support is not compatible with the mainboard...

Do you have a solution please?

Thanks. This is my system:

Coolermaster 690
Intel i7 2600K Quad OCd @ 4.6 Ghz
ASUS Sabertooth P67 Motherboard LGA 1155
Antec Kuhler H2O 620 Liquid Cooler
Corsair Vengeance 16GB @ 1333 Mhz
Zotac GTX 550 TI AMP 1024GB
Corsair 650W
M4 SSD 64GB 6Gb/s (Boot)

Since you got it, hows it doing? I'm think of getting one! And it is LGA1155 compatible, right?

Since you installed it yourself, do you think I could add a fan to make it a push-pull setup like the Corsair H90? Sandwich the radiator between two fans, one pushing air in, the other pulling it out, out the back of the case? Oh, I see you did that!

Biggest question is: are there screw holes on both sides of the radiator to mount fans?

I just ordered one, and YES, you can set up push-pull!

I posted a question here.
