Performance increase upgrading from h60 to h100i

Just curious as to how much of a performance increase I'll be seeing if I upgrade. Anyone know an approximate temperature decrease if I'm currently getting around 65C while playing games and 90C+ at full load running a i7-4770k with an h60? Ambient temperature in the room is around 20C if that matters!

Thanks :)

Core temp has offset in it and to have it show correct reading it has to be calibrated. I do on my rigs use it and take...

There's something wrong with that setup if you're getting 90+ degrees under a stress test.
I had a H60 and it really wasn't a bad cooler tbh I just wanted more room to OC.

Speaking of, is your chip overclocked? and if so, by how much?

The H100i is widely considered one of the best CPU coolers on the market. There are a few better, but not many. You will gain a very noticeable difference should you go down that route. How much exactly I can't really say, depends on your chip and case cooling etc...

Hey thanks for the reply! Alright I have to agree with you I personally think my temps are way too high. I actually brought it back in to the place where it was built and they said nothing is wrong with it so I figure I need to take matters into my own hands. Any idea what the cause of my temps is? Could it just be a faulty chip? I have excellent airflow to my case (corsair 230T) and I'm in the basement which as I mentioned before is very cool. I'm thinking about making the switch to an H100i because I'm at a loss of what to do!

Thanks for the link! This just makes me certain something is going wrong somewhere... It looks like I'm getting the same temps with a watercooler as I would be with the stock air-cooler :( Oh and by the way I'm not overclocking at all.

The H60 uses a standard 3 or 4-pin wire for power (I can't remember which it was, probably 4). This is convenient, but it also means there's room for error.

As you probably know, boards have the ability to change voltages to fans on-the-fly, reducing their RPM when things aren't stressful. With the H60's setup it's likely that the board is turning down the RPM of the pump without realising it's actually a pump. It's considered best to plug that cable into a SYSFAN header, or one that doesn't adjust speeds.

Of course also plug it into a 12v header, but on pretty much every modern board they're all going to be.

So solution then. Fire up... I believe SpeedFan worked. One of the readings will be the pump RPM. It will be fairly obvious since it'll be the only one with stupidly high levels (I seem to recall with the H60 that was in the 4000+ range). How many fans do you know that spin that fast? If it isn't, then there's an issue.

If it isn't. I would imagine making that particular header run at full speed in the BIOS would be the solution.



If it's not that. Remount the cooler and ensure that you remove any thermal paste before applying new stuff. (There are lots of tutorials for this, what to use etc...).
Fan orientation doesn't really matter with a radiator, but I'd advise that you have it in a pull config, in that it's pulling through the rad and exhausting out the back of the case.

So just throw my CPU fans on full speed in the BIOS? I assume that will result in quite a bit more noise but that's not really a big issue for me. I'll also look into plugging it into a SYSFAN if it isn't already (I'm not home atm unfortunately). Quick question, will having it set on PWM have any effect? Thanks a ton for your response man super helpful!

No no just the pump one. The rest work independently. There should be a setting in the BIOS to set each header depending on how you want it.
Find out if it's doing it first.

PWM is just a term for fans to control their own speed, ie 4-pin fans (That extra pin is what does it).

Ahh so my mobo might just be thinking my pump fan is like a regular chassis fan and throttling it back? Sorry about all the questions this is my first build and I didn't even do most of the work (although now I wish I had). And so the best way to see if its doing that is to use speedfan?

Indeed. It's a fairly simple fix if it is.
Like I said, just turn up that particular header to full speed. Peek inside the chassis to see which one it's plugged into, or SpeedFan might tell you. The cable comes right out of the block so it's not too difficult to see.

Hey so I finally got home and took a peek inside the case. It looks like my pump is plugged into CPU_FAN while the fan on the radiator is in CPU_OPT. I attached a picture of the RPM's that speedfan is giving me, does everything look normal? I guess if the RPM's aren't the issue I should try remounting.

Yes that does look normal actually. SpeedFan reads the pump as being in the SYSFAN header, which is the best spot for it to be in.

Temps look quite normal there too. You'd think if the cooler wasn't mounted properly you would be getting far higher idle temps than 28c.

Alright so I switched some fans around in my case but I think the issue was core temp was giving me completely wrong readings. I'm playing a game right now (Archeage) and core temp is saying I'm getting 60C while speedfan is telling me I'm getting 37C which would make a lot more sense. Should I be trusting speedfan over core temp here?
 


Core temp has offset in it and to have it show correct reading it has to be calibrated. I do on my rigs use it and take the temp in BIOS on cold start then check idle temp as soon as it is started and then set the offset on the temp difference. In 4 rigs my offset is from -22° to + 12°C.
