1366 socket 960 i7 OC on custom pc case heat problems

[makiscursing]

So , i have this old pc , but still running all games at ultra 1080p , and its very very fast at my tasks , but due to my new BIG GPU or due to wrong cpu OC settings my pc on max load becoming hot , 80c at 90 % , and with bios protection on the pc underclock when its on 80c and from 4.0 ghz goes to 3.2 but temps still high.. on idle I have like 47 c (c1 state disabled )and on gaming like 55c and 60c max

I know these temps for my socket + oc + my costum pc with bad airflow is impressive and fine , but i want to lower more my cpu temp and if we can mobo temp ( 60c constant on north bridge )



So far i have think few solutions and i need you guys tell me the best shot i have



1st , water cooling my cpu with one Corsair Hydro H80i v2 maybe ? or any other type ?

2nd is removing my old i7 960 , buy one used from ebay xeon with 6 cores , OC back to 4 ghz , and thats all ? temps will be lower?

3nd is to complete change my pc case airflow ? i have 3 high cfm 12 cm fans for intake , and 1 14cm high cfm for exhaust , maybe adding one more for exhaust will help a lot ?

4th option a mix of all of them maybe ?xD



so guys what you think is the best ?

Note : I have already reapply thermal paste on cpu with one very very high quality , temps drop about 10c because i had 4 years to change the thermal paste xD

Also i tried Underclock my cpu a little , but windows wont boot , also i have set most of settings to auto , and enabled c states and dynamic voltages so the mobo change the voltage it self and this means less heat when i dont use the pc , if i will disable all this C states and EIST and all these protections and set the voltages manually im sure temps will go very high



any idea is welcome , help me guys avoid getting new mobo +cpu+ram (about 700 euro or more )

Explain how airflow works in that please. I see only the one fan.
You need air blowing into the motherboard area and another fan sucking the hot air out.

The fan on the CPU cools just the CPU. You need either a good intake fan or 2 to bring in cool outside air, or 1 or 2 exhaust fans to remove the heated air.
Also air flow over the VRM MOSFETS is important also. This usually favors intake fans.
One Xeon you might look at is the X5687 which is a 32nm 4 core 8 thread 3.6/3.89 GHz CPU.
That looks like it was built into the bottom of a desk drawer. Cool air in, hot air out. make sure it can't just loop back around and come in again.

I have 3 fans of 12 CM with very high airflow for intake and 1 14 CM for exhaust, but the 3 fans does not hit direct the vrm s or the mobo, the air is above mobo, air hit directly gpu and cpu and psu.... Maybe I need to make fans hit direct mobo? At least one of the 3? About the water cooling for cpu is bad idea? It will. Increase the airflow once this huge cooler will gone

Loss of VRM cooling is a common problem with water cooling. Not hard to solve as long as you're aware of it.
Unless you need 6 cores/12 threads the 32nm 4 core 8 thread Xeon should run cooler, and/or clock higher than what you have now.
You might look into a bigger cooler like the Scythe Ninja 4.

It's basically 120mm square with the fan added to any side.
