Quote[Mind you that all our tests are performed at a room temperature of roughly 21 Degrees C. We decided to go with the Core i7 4790K as it literally is the hottest processor your money can get you. You guys all know that once overclocked with added voltage, the temperatures get out of control big-time.

We've been battling the question whether or not to actually use a Core i7 4790K on a Z97 motherboard. The Haswell processors all have poor heat transfer from the silicon die to the IHS. Fact remains that this CPU is what the Guru3D audience buys -- and as such you -- would want to know how these coolers perform]quote

After reading Guru 3D review of the H150 Corsair cooler, I need to see what members think of my system temps.
I have that CPU in Asus Z97-Pro Gamer.
Asus GTX 980 Strix @ 4.4G
360 radiator with 2 X approx 900 rpm and 1 X about 1500 rpm.
The CPU has a good water block but can't find the details.
The 980 Strix is water cooled with EK full cover VGA water block EK-FC980 GTX Strix Acetal/Nickel.
Both waterblocks share the one loop.

Using Elite Dangerous with idle on the pad the cores ranged from 34 to 44 degrees centregrade.
Whilst flying and fighting, the highest was 64 degrees.
In the past, on a hot day, 30 degrees ambient, the temp did reach 78 celcius.
The ambient for this temp was about 26 degrees.
The ambients mentioned are in my computer room.

 

Are there better CPUs for this board that run cooler?

Or should I de-lid and risk destruction?

78c @ 4.4Ghz isn't bad for a Haswell. Pretty much unless you delid or lower the CPU voltage, You cant get much better results. Those Haswell chips really warm up with any increase in voltage over 1.15~ (stock).

Your chip is fine running at 65c, and real world stress on a hot day being 78c,.. no need to worry till you reach 90c.

 

Delid is the way to go if you want better temps,.. delided your chip should do 4.7GHz @ 1.2V around 70-75c under load.

 

Your motherboard supports Xeon chips,.. the Xeon E3-1286 v3 would be only chip close to your i7-4790K,.. and would run a bit cooler running at default 84W 3.7GHz,.. you would be taking a huge performance hit running lower wattage Xeons,.. so your better off sticking with your i7-4790K.
