Intel Ivy Bridge CPU's Are Proven To Suffer From Poor TIM Choice
Intel Ivy Bridge CPU高溫問題被證實肇因於選用較差的散熱膏


Japanese tech site, Impress PC Watch, has proven what many have suspected:
Intel's Ivy Bridge CPUs suffer high temps due to a poor thermal interface
material (TIM) choice. Why Intel decided to use TIM instead of solder is
unknown but what was discovered is that by replacing the cheap thermal compound
with better alternatives yielded significant temperature drops.
日本科技網站，Impress PC Watch，已證明許多人曾經的質疑：Intel Ivy Bridge CPU
之所以高溫乃因使用了較差的散熱膏。為什麼Intel決定使用散熱膏而不是焊接仍不了解，
但發現將原廠散熱膏換成較佳的替代品能明顯降低溫度。

They compared the stock TIM with OCZ's Freeze Extreme and Coollaboratory's
Liquid Pro while using a Thermalright Silver Arrow SB-E as the cooler of choice
They then compared all three TIMs at stock 3.5GHz and overclocked at 4.6GHz
1.2v.
他們選擇了OCZ's Freeze Extreme以及Coollaboratory's Liquid Pro這兩款散熱膏和原廠
的做比較，散熱器則使用利民銀箭SB-E版本。比較三款散熱膏在預設時脈3.5GHz和超頻至
4.6GHz(核心電壓1.2v)的表現。


At stock clocks and stock TIM the I7 3770K hit 61℃ while the OCZ TIM dropped
temps to 53℃ and the Liquid Pro TIM dropped temps down to 50℃ that's a full
8-11℃ lower then the stock TIM Intel used. While overclocked to 4.6GHz the
load temps with stock TIM skyrocketed to 84℃, meanwhile the OCZ TIM dropped
temps down to 69℃ with the Liquid Pro dropping temps all the way down to 64℃.
That means at full load and overclocked simply replacing the TIM used saw temps
drop an insane 15-20℃. As it stands replacing the TIM on most enthusiasts CPUs
wont be likely due to the simple fact it will void their warranties, however,
this does prove that Intel has cheaped out on the thermal interface material.
The only reason for this action that comes to mind is to keep Ivy Bridge from
cannibalizing Sandy Bridge E sales.
預設時脈下，I7-3770K配原廠散熱膏會達到61度C，而OCZ和Liquid Pro則分別能降至53
度C和50度C，足足低了8~11度C。超頻至4.6GHz後，原廠散熱膏猛升至84度C，而OCZ和
Liquid Pro則分別能降至69度C和64度C。這意味著只是換掉原廠散熱膏就能狂降15~20度C
，但顯然大家不太可能這麼做因這會使保固失效。然而，這次實驗證明Intel選擇了廉價
散熱膏來用。此舉腦海中浮現的唯一理由就是避免Ivy Bridge侵蝕Sandy Bridge-E的銷路
。
