REVIEW: Scythe Infinity Cooling Mini Fans Review

post #1 of 8
Thread Starter 
Hi.

This Round-up is basically for me to compare a few cooling options I have at my disposal for overclocking purposes, for this reason I will NOT use stock speeds on my q6600, instead for the first test i will use 3.2Ghz @ 1.3625v and 3.6Ghz @ 1.4875v. This is also for me to see the difference in temps caused by adding a second fan. In my opinion the highest acceptable temps for my 24/7 rig is 72C.

First of all I have already started logging down the results of this test so far so I might as well share them. I will update this as I go.

My goal is to find out the best out of;
Single Stock Scythe Infinity Fan
2 x Stock Scythe Infinity Fan

I remembered to take the picture AFTER I cut the cable ties... lol
Single Noctua NF-P12 Fan


After that is done, I will then apply Noctua NT-H1 to the best fan/fans combo and then see how much of a difference I will get at 3.2Ghz and 3.6Ghz then hopefully try to get to/above the magical 4.0Ghz


TEST SYSTEM: Refer to sig rig. Ambient Temps: 21-23C

TEST 1: Best Fan Combination

STEPS:
1. Boot PC with 3.2Ghz to 3.6Ghz settings
2. Allow for PC to idle 10 minutes, log temps
3. Play COD4 level* (Charlie Don't Surf) for 10 minutes, log temps
4. Allow 10 minute cooldown (sitting at desktop idleing)
5. Run PRIME95 25.6.1 (4 threads, Small FFTs), log temps
6. Repeat for each fan combo

TEST 2: MAXIMUM OVERCLOCK + TEMPS

STEPS:
1. Overclock PC to the MAXIMUM possible.
2. Allow for PC to idle 10 minutes, log temps
3. Play COD4 level* (Charlie Don't Surf) for 10 minutes, log temps
4. Allow 10 minute cooldown (sitting at desktop idleing)
5. Run PRIME95 25.6.1 (4 threads, Small FFTs), log temps
6. Repeat for each fan combo

TEST 3:

STEPS:
1. Chuck all remaining spare fans in, Log temps
2. If good enough, overclock more!

RESULTS:

TEST 1:

1 x Scythe Infinity Stock Fan

@ 3.2Ghz 1.3625v
Idle: 48C
CoD4: 56C
PRIME95: 69C

COMMENT: Barely acceptable in PRIME95...

@ 3.6Ghz 1.4875v
Idle: 51C
CoD4:66C
PRIME95:80C FAIL!!!

COMMENT: The 80C was hit almost immediately which is definitely above 70C so it failed the test.

2 x Scythe Infinity Stock Fan

@ 3.2Ghz 1.3625v
Idle: 45C
CoD4:55C
PRIME95:69C

COMMENT: Not so much improved.

@ 3.6Ghz 1.4875v
Idle: 47C
CoD4: 63C
PRIME95: FAIL! 75C

COMMENT: Not surprised...

1 x Noctua NF-P12 @ 3.2Ghz 1.3625v

Idle (after 10 min): 42C
Call of Duty 4 (10 minutes): 53C
Small FFTs (30mins): 68C

COMMENT: Extraordinary for 1 fan only!

1 x Noctua NF-P12 @ 3.6Ghz 1.4875v

Idle (after 10 min): 47C
Call of Duty 4 (10 minutes): 61C
Small FFTs (30mins): FAIL! Instantly Hit 72C

COMMENT: Same as above comment. I wish I got a second one now.

TEST 2:

I have declared the Noctua NF-P12 the winner as it has similar results, sometimes better, to the 2 x Stock Scythe Fan and there is room for one more.

Noctua NF-P12 + NT-H1 @ 3.2Ghz 1.3625v
Idle (after 10 min): 40C
Call of Duty 4 (10 minutes): 53C
Small FFTs (30mins): 69C

COMMENT: I’m disappointed by the minimal Difference.

Noctua NF-P12 + NT-H1 @ 3.6Ghz 1.4875v

Idle (after 10 min): 47C
Call of Duty 4 (10 minutes): 58C
Small FFTs (30mins): FAIL: Hit 72C in small steps.

COMMENT: At least it didn’t immediately jump up to above 70C

TEST 3:

A final test so that I can hope to get some benefit out of this which I have gotten minimum right now . I have added the two Scythe Fans as case fans and hopefully it can wipe off a few more degrees.

Noctua NF-P12 + NT-H1 @ 3.6Ghz 1.4875v

Idle (after 10 min): 42C
Call of Duty 4 (10 minutes): 55C
Small FFTs (30mins): PASS!: Slowly hit 70C

COMMENT: The CPU temps are slightly better but one good thing to this is that my Nvidia 780i MCP used to IDLE around 69C and now they idle about...58C!!! My 8800GT used to idle in the 50s now its around 45-48C

CONCLUSION:
In the race to lower temps and everything, every degree counts. I have learnt that the following reduces the temps;
Add a fan with better pressure
Add another fan
Add better thermal paste (slightly better)
More case fans!!!

The best cable hiding in the WORLD...

...Still needs some work

And another point to make is that these results are for my rig where I live, unless you have a 100% identical rig and environment (and lack of skills) as me, you will most likely not get the same results as me!!!
What I’ll be doing the next few months;
Writing an article about how to make my PC shut up now its got more fans
Debating against myself about what upgrade I can get (also a thread about it)
Trying to mod my speakers (currently still on drawing board... )
I would LOVE some feedback on how I can improve the writing of this so feel free!

Another Question
Is this a good thing to see when you look at the bottom of your heatsink?


One last thing, if somebody can think of a better name for this thread and can tell me how to change the thread name... tell me!
Oh and, how do I add graphs from excel into this? THANKS

*10 minutes of Charlie Don't Surf level involves starting the mission in Regular difficulty (so minimal chance of dieing, I usually play in VET/Hardened) and simply playing 10 minutes of it, usually I get to the end of the level. I chose COD4 because I currently don't have Crysis installed yet and not to mention there are a lot more bullets flying in CoD4! And Assassin's Creed is a little bit buggy on my rig!

Hopefully you'll all enjoy reading this!

Sounds like a great set of benches! I am interested to see what temperature's you get considering I have a Q6600 myself. (Which I'm having problems with overclocking )

This is for a simple to read update log of what happens. Should have reserved a post. (Makes mental note of it)

UPDATE: Stock Fans 3.2Ghz idle temps added

UPDATE:Stock Fans 3.2Ghz CoD4 temps added

UPDATE: PRIME95 3.2Ghz temps added

UPDATE: CoD4 Temps for Scythe Infinity @ 3.6Ghz

UPDATE AGAIN: Starting PRIME95 now.

UPDATE AGAIN: Forced to Cancel PRIME95 immediately as temps hit 80C instantly

UPDATE: Installing 2nd fan

UPDATE: Testing Now 2 Scythe Fans now!

Sorry for double post.

Does anyone want to make any guesses for how high the q6600 with Scythe can go before I run the test?

Done, the review is now finished and there is nothing else to add except for pictures and if someone suggests something to add.

I had the Scythe Infinity with an NF-P12 Noctua fan on it, and I still couldn't stand it. The thing is just too big. I cut my hands up trying to mount the thing. Plus, my HDT-S1283 performs a few degrees better and it's about half the size.

DUDE, that last picture looks like you forgot to peel off the plastic cover off of the heatsink.

Yer I figured as much... next time I"LL install the CPU... not my 'reliable' friend. As far as I can tell, the image seems to like already be melted into the heatsink. I don't think there is a way to peel it off, I have tried but to no avail so... has the plastic melted into the copper? I really wish I had a better camera to take the photo with! The base is smooth and it seems like ...wierd. It is slightly purple in the centre where the old TIM used to be and there seems to be one small bubble-a-like thing on the side. Would you be able to have a look through my results and figure if the temps are reasonable or not? Thanks. The only way that I figure I can solve this is to lap it.

I have thought about getting a better cooler but I can only get one upgrade (I'm not rich...) so I am asking the helpful people of OCN to help out @ http://www.overclock.net/graphics-ca...-please-2.html about which upgrade in the poll I should choose to get.
