cpu cooler ID-Cooling SE-903

[2spooky]

I'm buying this cooler from a guy who bought himself an i5 6600K and got it as a gift with it , and he's selling it for half price.

I have an i5 3470 with the stock cooler from an i3 3240 (without the copper bottom) and i don't really like my temps , after 4 hours playing GTA5 , my highest core was 71C and the rest 69 68 67 and i have 21C in my room in winter.

My question is , will ID-Cooling SE-903 do a any difference ? I just want my CPU to don't pass 67C in gaming in full summer when i have 30C in my room

Should be better than stock cooler, by how much remains to be seen yet when summer comes. Adding another fan may help for few degrees to.

Ok , so I mounted to cooler and everything is fine and cool , after 5 mins of prime95 the max temp was 58C , huge difference from the stock cooler , but there's a tiny problem, the fan has a 3pin connector and it goes at max rpm all the time , 2500rpm , it doesn't sound so loud but there's a specific sound , i can get over that.

It's strange cause on the manufacturer website it doesn't even mention about the fan connectors , only says "fan rpm 2000" even that it's not true cause mine goes at 2500 , but whatever.

You could replace fan/s with a PWM fan/s or ad a controller but comes summer you may be thankful for those extra 500 rpm.

What do you guys think i should do to have a better airflow in my case and better temperatures?
This is my current setup of fans http://i.imgur.com/ODCjWMB.jpg

I removed my 80mm exhaust fan from the back cause it made too much noise , i'm thinking to buy a silent 80mm and put it as exhaust in the back and turn my cpu cooler to exhaust too, do you think it's a good idea or should i let them as they are now ?

 

[CountMike]

Ugh, wrong for most part.
CPU and back exhaust fans should blow out. CPU fan to other side so it also blows thru cooler body. Front and side to push air in. Don't count PSU for removing much air out of the case, it's mostly sufficient only to cool itself.
With CPU fan turned other way in conjunction with back case fan, it will cool VRM too, Side fan should provide fresh air to GPU and chipset.

I tried to move the fan on the other side of the CPU radiator but it won't fit , so i have to remove the whole cooler and move it so it acts like an exhaust , i will do that when i get my thermal paste which i ordered last week. For the side panel fan i think it's good to act like an exhaust cause the GPU gets air from the bottom part of the case, right where my front intake fan is , so it gets cool air for it and the GPU blows the air literally the way where the side panel fan is so that's why i'll let that one as an exhaust.

The only thing i'm gonna change is the cpu cooler , gonna put it that way to act like an exhaust and blow through the radiator and i might get a 140mm fan for the side panel so it has better CFM , this one i have now it's a cheap 120mm fan @1200rpm with 23cfm but it's silent though. The only fan which wasn't silent was the 80mm one from the back which i removed because of that.

 

[CountMike]

I would use side fan to blow in because like this, blowing out, it takes some flow from GPU and doesn't help chipset any.

I've decided to change my cpu fan cause i can't be asked to hear that tiny little noise in the background even when i'm browsing since my 3pin fan always spins @2.5k rpm

Is this a good fan ? http://www.coolink-europe.com/en/categories/23_26.html and will i be able to mount it on the radiator ?

 

[CountMike]

I don't know those but that 92p has 4 pin PWM connection that should be more adjustable. It make sense only if you have 4pin on the MB.

 

[2spooky]

My mb has 2x4pin slots , 1 is used by my front intake 120mm fan which goes up to 1350 rpm if it's too hot in my case (usually in the summer) and my other 4pin is near my cpu cooler and now it's used by the 3pin fan @2.5k rpm. I'll buy that fan which i linked , it says it goes up to 1.9k rpm and it has 4pin so when i don't play games it should spin around 1000rpm like my stock cooler did and it should be silent.

 

[CountMike]

That should work.

 

[2spooky]

So i replaced the cpu fan with that coolink fan and i turned around the whole cpu so it will act like an exhaust and i got huge improvement, temps in high load gaming haven't passed 58C and only on 1core , the rest of them were 53-55C and i applied a cheap thermal paste. I'm glad now that the new fan acts like it should and it's silent even at max rpm which is 1.9k.
I don't know why there was only 1core @58C , isn't there too big of a difference between them ? 53C and 58C ? I applied the thermal paste in a wrong way or why ?

 

[CountMike]

There's usually some discrepancy to core temps, 5c is not too much. If you applied paste wrong you wouldn't get such good temps at all. It takes few days for cheap paste to settle down, you may expect even lower temps than. Other than that difference between cheap and most expensive paste is usually only couple of degrees. Only Prolimatech Liquid and such stuff can mean 5 - 10c.

Thanks for the answers , now everything is going as i wanted , my PC is silent even in games and my temps are very decent i would say , strangely my r9 270x oc didn't go over 57C since i changed the position of the cpu cooler to act like an exhaust , before that my gpu would go up to 61C in gta5.
I'm waiting for summer to check my temps when i'll have 30C in my room.

I've tested my cpu 6 minutes in prime95 and i got these temps http://i.imgur.com/M6FcHns.jpg. I feel like i didn't apply the thermal paste properly , core #2 is always hotter by 4-5C degrees , i thought because cores aren't used evenly in games but in this test all cores were 100% for 6 minutes yet i get different temperatures , is this normal ?

 

[CountMike]

It's not too large difference and may need more than 6 minutes of ~100% load to equalize temps. Processor is actually under metal cover and is only something like 10 x 15mm, much smaller than the cover and there's no way you could have missed paste over just one core. There could be bunch of reasons for discrepancy, from wrong sensor to wrong readings. As long as your highest temps are not too high you should be all right.
