1. 발열
컴퓨터라는 기계는 오랜 시간에 걸쳐서 제법 많은 종류를
만져 봤지만, 정작 노트북은 많이 만져 본 경험이 없습니다.
저의 첫 노트북은 JVC 7220kr 이라는 8.9인치 짜리 P3-866 이었는데
아시는 분은 아시겠지만, 이 녀석은 A5 사이즈라는 작은 크기 덕분에
무시무시한 발열을 자랑했었지요. 2003년 2월 산인데...
지금도 제 동생이 동영상 강의 용으로 아무런 문제 없이 사용하고 있습니다.

그 다음으로 산 노트북이 T60p 입니다.
T60p는 덩치가 다소 큰 노트북이기에 발열은 그렇게 신경쓰이지 않더군요.
그래서 아무런 생각없이 잘 사용해 오다가,
서브노트북으로 X31을 구매를 했는데, 이 녀석은 나름 발열이 좀 있었습니다.
CPU에 로드가 걸릴때 마다 팬이 신나게 도는 걸로 봐서는 역시나
아담한 체구 때문에 쉽게 열을 받는구나 라고 생각을 했더랬지요.

얼마전에 구입한 X61t 역시 같은 크기의 X 시리즈 노트북이라
구체적인 발열 수준이 궁금했습니다.
하드디스크 부분에서는 열을 느낄 수 없어서 따로 체크를 해 보진 않았고
HD Tune으로 돌려본 게 전부이지만, 우측 팜레스트의 발열이 신경쓰이더군요.
HMM을 뒤져 보니, 무선랜과 블루투스 모듈, 터보메모리가 위치하고 있는 자리였습니다.
음... 따뜻할 만도 하군..
가장 열을 많이 내는 부분이 CPU니까... 본격적으로 테스트를 해 보았습니다.
보통 스트레스 프라임이라는 프로그램으로 테스트를 많이 하는데
이 프로그램에서 사용하는 루틴은 루카스-레머 판정법을 사용하여
메르센 소수(prime)를 찾는 프로그램이더군요. 그런데 오래된 프로그램이라 그런지
멀티 스레드를 지원하지 않아서 동시에 두개를 실행시켜야 한다는 단점이 있습니다.
그리고 하드디스크까지 억세스 하진 않더군요.
제가 만든 원주율(pi)를 구하는 프로그램을 몇시간 돌리는게 나을 것 같아서
어제 밤에 6시간을, 오늘 낮 4시간 동안 돌려 보았습니다.

제가 사용하는 X61t의 시스템 구성은 다음과 같습니다.
X61t 7764-A14, RAM 3G, HDD 200G(SATA2, 7200rpm, 16M cache, Seagate)
파워매니져 최대 성능모드 사용
주변 온도(기온)는 24도 정도.

1) 부팅완료 후(1시간 동안 전원 OFF 후 ON): 49도~50
-> 모든 부팅이 완료되고 cpu 로드가 0% 가까이 떨어졌을 때, 하드의 억세스가 끝났을때 입니다.

2) 최저 온도: 부팅 종료 후 대략 2~3분 안에 43도까지 하강
-> 억세스 컨넥션, 파워매니져를 비롯한 기본적인 ThinkVantage 프로그램 로드, 카스퍼스키 인터넷 시큐러티 로드

3) 최고 온도 (양쪽 코어 다 100% 상태로 진행)
-> (1) piano000 침대 이불 위에서 6시간: 55도까지는 급격하게 올라가나, 그 후로는 서서히 69도까지 상승하여 유지
-> (2) piano000 사무실 책상 위에서 4시간: 마찬가지로 55도까지는 급상승, 그 후로는 서서히 67도까지 상승하여 유지

4) 메모리
메모리는 하판쪽에 있어서, 자세한 온도측정은 불가하고 손으로 측정 -_-;;;
CPU가 100% 상황에서 밑바닥 따뜻했음...
노트북 들고 이불이나 책상면을 만져 보면 그냥 미지근한 정도였음.

발열 테스트에 대한 제 나름대로의 결론은......
사람이 살 만한 온도에서 작동을 하는거라면 발열에 신경쓰지 않고
막 써도 상관 없겠구나
라는 생각이 들었습니다.
L7700 이 T 시리즈의 CPU보다 저전력 저발열 설계라고 알고 있는데,
T7400을 사용하는 T60p와 비교해 보니, 최저 온도가 훨씬 낮더군요.
T60은 최저 온도가 50도 정도 됩니다.

2. 하드디스크
원래 기본적으로 따라 오는 하드디스크는 Hitachi 의 250G 5400rpm, 캐쉬는 8메가 짜리였습니다.
하지만 조용한 곳에서 들으니 소리가 계속 거슬려서
Seagate의 SATA2 방식의 200G(7200rpm, 16M cache) 로 교체를 해 주었습니다.
소음이나, 속도 등 모든 면에서 교체해 준 하드가 월등히 나은 성능을 보여 주더군요.
T60p에서 사용중인 Hitachi 7K200 160G (SATA1, 7200rpm, 16M cache)와 비교하면
근소하게 앞서고 비스타 체험지수 역시 시게이트쪽이 약간 높게 나오더군요..
(시게이트가 5.5, 히타치 7k200이 5.3 나옵니다.)
HD Tune 결과를 첨부합니다.
