Six core 3930k 3.2GHz OC @4.3GHz

Hi

I recently ordered a custom built PC. Here are the specs:

Case NZXT PHANTOM 410 WHITE GAMING CASE

Overclocked Intel® Six Core i7-3930K @4.3ghz

ASUS® P9X79: INTEL® SOCKET LG2011

32GB KINGSTON HYPERX GENESIS QUAD-DDR3 1600MHz X.M.P(8 x 4GB KIT)

2GB NVIDIA GEFORCE GTX 670 - 2 DVI, HDMI, DP - 3D Vision Ready

120GB INTEL® 330 SERIES SSD, SATA 6 Gb/s (upto 500MB/sR | 450MB/sW)

2TB WD CAVIAR BLACK WD2002FAEX, SATA 6 Gb/s, 64MB CACHE (7200rpm)

CORSAIR 750W ENTHUSIAST SERIES™ TX750 V2-80

Processor Cooling:

SPIRE GEMINI REV.3-THERMAX HDT TWIN FAN CPU COOLER

ARCTIC MX-4 EXTREME THERMAL CONDUCTIVITY COMPOUND


Everything runs really well and the temperatures are stable on all the components. However, it has been suggested that the temperature of my CPU is way too high.

Tests: IDLE - 4325 MHz and 1.360v

Real Temp GT - 48C
ASUS AI - 40C
SpeedFan - 48C
Core Temp - 48C

Tests: 100% Load - 4325 MHz and 1.360v

Real Temp GT - 88C
ASUS AI - 56C
Speedfan - 86C
Core Temp - 87C

I need some guidance here. What do I do to reduce the temperature? Without reducing performance?
